radio button group, average values from 1 - 5, done. I can even auto format a summary text field and highlight appropriate summary responses BUT, I have been given two caveats for the average summary. IF a 2 is present, the value will be 2. IF a 5 is

I am adding the following so you may see what is working and where. Restating my question at the bottom.

// definition of document level functions;
// filter callbacks used to select elements to keep in an array;
function isNotNull(element) {                    // remove null values array;
  return String(element).length != 0;
  }
function isNotNaN(element) {                   // remove NaN values from array;
   return element = !isNaN(element);
   }
// end filter callbacks;
function aAverage(aNumbers) {                 // average values in array;
var nSum = 0;
for(var i = 0; i < aNumbers.length; i++) {
    nSum +=Number(aNumbers);
    }
var nAverage = "";
if(aNumbers.length > 0) {
    nAverage = nSum / aNumbers.length;
    }
return nAverage;
} // end aAverage function;
function aFieldNames2aValues(aNames) {   // put the values of named fields into an array;
    var aValues = new Array();
    for(var i = 0; i < aNames.length; i++) {
aValues.push(this.getField(aNames).valueAsString);
    }
    return aValues;
}
function AverageFieldNames(aFieldNames) {
    var aValues = aFieldNames2aValues(aFieldNames);
    aValues = aValues.filter(isNotNull);     // remove null values;
    aValues = aValues.filter(isNotNaN);    // remove Not a Number values;
    return aAverage(aValues);                 // compute average;
}                                                             // end aAverageFieldNames function;
// end function definitions;

At the form level, insert this into the custom calculation script field for the section summary average

// custom calculation script;
var aFieldNames = ["Q7", "Q8", "Q9", "Q10", "Q11", "Q12", "Q13", "Q14", "Q15", "Q16"];
event.value = AverageFieldNames(aFieldNames);
// end of custom calculation script; 

In the custom format script of the same text box that is calculating the section average, insert the following. This will make the correct ‘BOX’ highlight appropriately.

The below begins “BoxA2” because this was pulled from the second section. First section would be BoxA1.

if((String(event.value) == "") || (event.value == 0))
{// No Entry
this.getField("BoxA2").value = "Off";
this.getField("BoxB2").value = "Off";
this.getField("BoxC2").value = "Off";
this.getField("BoxD2").value = "Off";
this.getField("BoxE2").value = "1";
}
else if(event.value >= 4.5)
{
this.getField("BoxA2").value = "5";
this.getField("BoxB2").value = "Off";
this.getField("BoxC2").value = "Off";
this.getField("BoxD2").value = "Off";
this.getField("BoxE2").value = "Off";
}
else if(event.value >= 3.5)
{
this.getField("BoxA2").value = "Off";
this.getField("BoxB2").value = "4";
this.getField("BoxC2").value = "Off";
this.getField("BoxD2").value = "Off";
this.getField("BoxE2").value = "Off";
}
else if(event.value >= 2.5)
{
this.getField("BoxA2").value = "Off";
this.getField("BoxB2").value = "Off";
this.getField("BoxC2").value = "3";
this.getField("BoxD2").value = "Off";
this.getField("BoxE2").value = "Off";
}
else if(event.value >= 2)
{
this.getField("BoxA2").value = "Off";
this.getField("BoxB2").value = "Off";
this.getField("BoxC2").value = "Off";
this.getField("BoxD2").value = "2";
this.getField("BoxE2").value = "Off";
}
else
{
this.getField("BoxA2").value = "Off";
this.getField("BoxB2").value = "Off";
this.getField("BoxC2").value = "Off";
this.getField("BoxD2").value = "Off";
this.getField("BoxE2").value = "1";
}
// set target field color to default values;
if((String(event.value) == "") || (event.value == 0))
{
event.target.fillColor = color.transparent;
}
else if(event.value >= 4.5)
{
event.target.fillColor = color.green;
}
else if(event.value >= 3.5)
{
event.target.fillColor = color.blue;
}
else if(event.value >= 2.5)
{
event.target.fillColor = color.yellow;
}
else if(event.value >= 2)
{
event.target.fillColor = color.red;
}
else
{
event.target.fillColor = color.transparent;
} 

The last bit above formats the fillcolor of the text box that is holding the average calculation. This one box is getting a lot done.

I am curious about one bit above. At the document level, I have adjusted the color.blue to be,

fillColor.blue = ["RGB", 0, 1, 1]; or light blue. I also tried using “RGB”, 124,218,252

and

I also changed the font color.blue = ["RGB", 0, 1, 1];  BUT while the text colors are resulting as a nice light blue, the fill colors are remaining dark blue… obscures the black numbers in that field. Right now, this is a curiosity and the least of my issues.

Any suggestions on how to set the event.value to 2 if a 2 is present in any radio button group or to set the event.value to 5 if a 5 is present and no 2 is present in any radio button group?
