My form has checkbox that when "checked" should prevent other checkboxes from being displayed. Have tried several variations of code without success. Latest version is:
 
var a = this.getField("Q2a"); //Checkbox to be hidden
if (this.getField("Q1").value == "Yes") //Checkbox used to make show/hide determination
a.display = display.invisible; //hide checkbox "Q2a"
else
a.display = display.visible; //show checkbox "Q2a"
 
Have tried to use "show/hide" function in "Actions" menu for checkbox "Q1" however system goes busy using 100% of memory for five+ minutes when bringing up show/hide fields menu. Decided to use java script instead. Can anyone verify the syntax/code for me? Thank you in advance.

That should be:

a.display = display.hidden;


For more information, see: "display" field property documentation

Where exactly did you place that code? Are any errors shown in the JavaScript console (Ctrl+J)?

George, thanks for the help. Opened Javascript console to find that Q2 was not defined.... syntax error in the code. Should have been "Q2a". Thanks for helping me to get this to work.
