button click to show field only if text field is populated

I understand how to show and hide fields with a button click. But, what I'm trying to do is, click a button and to show a field only if that field has a calculation from other fields. If no info is calculated from the other fields, then the field in question would remain hidden no matter how many times I click the button. But then, the fields that have been populated would show leaving the un-populated fields hidden. Can this be done? Here's a couple of scripts I've been playing around with but I can't get to where I want to go using them.

Script:

  this.getField("Item.1").display = display.hidden;

and/or,

if (this.getField("Item.1").valueAsString=="") event.target.display = display.hidden;

else event.target.display = display.visible;

Would someone teach me the correct script to do this and to help me out? Thanks.

Not really... Why would you need to hide a field that is empty? But never mind. You can do it like this:

var f = this.getField("Item.1");

f.display = (f.valueAsString=="") ? display.hidden : display.visible;

So you want to hide a field if it has no value, basically?

Hello, the fields I'm referring to sometimes have a sum, sometimes they don't. When they do I'd like to show them, but when they don't have anything in them they remain hidden. Only the fields which have a sum will show when I click the button. Is it possible? Know what I mean.
