Loop syntax

is there any reason this code would not work on a button?

var f = this.getField("Installation");

var a = f.getArray()

for (i=0; i < a.length; i++){

if (a.valueAsString != null) {

createSheet();

}

I have handfull fof filelds with installation in name and i'm checking to see if any of those fields have data.

"Installation" needs to be more than just in the name. It has to be a dotted prefix.

Like this

"Installation.text1", "Installation.text2", etc

Yes. If you access valueAsString it will never return null. If the field is empty it will return an empty string.
