Hello!

I am trying to do a custom calualtion script for a pdf. 

I have the value "weight" that I am inputting into the form. 

I want the box name O2Min to calulate "Weight" *50 to give a result in that O2Min box. However, if that calulated value is below 0.5, I want the box to display 0.5 becasue it can't drop below that for safety reasons. Can someone help me write this out?

    You can read about writing calculation scripts here:

    Use this script in the calculation for the "O2Min" field

    var nRslt = this.getField("Weight").value * 50;
if(nRslt < 0.5)
  nRslt = 0.5;

event.value = nRslt;

    Note that the code above will cause 0.5 to show even when Weight is empty... Not sure if that's what you wanted to achieve.

    Well, lets get that fixed up.

     

    var cWt = this.getField("Weight").valueAsString;
if((cWt == "") || !isNaN(cWt))
   event.value = "";
else{
   var nRslt = Number(cWt) * 50;
   if(nRslt < 0.5)
      nRslt = 0.5;

   event.value = nRslt;
}
