I keep getting these errors. I've gone back and copied/pasted field names exactly, but can't correct. Any guidance greatly appreciated!

Here's the checkbox field 'mouse-op javascript' I'm using.

if (event.target.value == "or") {

// box is checked
this.getField("RBCoOwnerResident82040").display = display.visible;
this.getField("RBCoOwnerCitizen82040").display = display.visible;

You can get the information about the missing fields when you define following function:

function f_getField(name)
{
	var fld = this.getField(name);
	if (!fld) {
		console.show();
		console.println("Missing field: '" + name + "'");
	}
	return fld;
}

Use the function like this:

f = f_getField("RBCoOwnerResident82040");
if (f) f.display = display.visible;

Hi Try67; did that and also cut/pasted names directly into script. Nothing corrected the issue. Removed phone field fomat. Even substitued 'Date' fields with Text fields formatted with a date setting mm/dd/yyyy. Also tried running the scripts individually. Nothing changed, still the errors I mentioned earlier. Other suggestions? Thanks in advance- kemper

Those errors mean you specified an incorrect field name. Go to the number line indicated (11, 31, etc.) and check around it if any of the names you used are not typed correctly. Even a single character off (like "O" instead of "o", or a space) will cause it to fail.
