    Use this code as the custom calculation script of your field:

     

    var a = this.getField("group 1").valueAsString=="No";
var b = this.getField("group 2").valueAsString=="No";
var c = this.getField("group 3").valueAsString=="No";

if (a && b && c) event.value = "Thank you...";
else event.value = "Sorry...";

    I would like a text box where numbers are entered and if a certain number is entered, a specific hidden Template will populate.  Can you please help me with the coding? This is what I have so far, but it will only populate the last template.  The first two aren't populating no matter what number I enter.

    var a = this.getField("Signing1-9").valueAsString=="1";
    var b = this.getField("Signing1-9").valueAsString=="2";
    var c = this.getField("Signing1-9").valueAsString=="3";
    var d = this.getField("Signing1-9").valueAsString=="4";
    var e = this.getField("Signing1-9").valueAsString=="5";
    var f = this.getField("Signing1-9").valueAsString=="6";
    var g = this.getField("Signing1-9").valueAsString=="7";
    var h = this.getField("Signing1-9").valueAsString=="8";
    var i = this.getField("Signing1-9").valueAsString=="9";
    if(a && b && c)event.value=this.getTemplateAsString("Regulatory").hidden=false;this.getTemplateAsString("Signing1-3").hidden=false;
    if(d && e && f)event.value=this.getTemplate("Signing4-6").hidden=false;
    else event.value=this.getTemplate("7-9").hidden=false;

    As the custom calculation script of the comments field enter the following code:

     

    var a = this.getField("A").valueAsString=="Off";
    var b = this.getField("B").valueAsString=="Off";
    var c = this.getField("C").valueAsString=="Off";
    var d = this.getField("D").valueAsString=="Off";

    event.target.required = (a || b || c || d);

      Please help me with one more thing:

      I have 3 questions with Yes/No choice. I have created group 1, group 2 and group 3. If the answer for all the 3 is No then i have to display a message " Thank you ......" and if any one is Yes then the display message will be "Sorry ...". How do we display these messages? Thanks in advance!

      As the custom Calculation script of your text field.


      I inserted a new text field inthe form and added the script to Custom Calculation script but after i select the choices for the groups it does not display the message in the text box. What am i missing? I have made it a read only field. Is it possible to display the message in this text box?

      Is it possible that I create 2 test fields and based on the condition above hide/unhide them?
