Ok. After playing around for a bit I figured it out. I ended up with this script. It will change the numerical field background color based on a positive, negative or neutral value and it will also display the positive/negative sign. With your help radzmar I was able to finish this. Thanks.var num1 ...

Yes. It does the plus and I added the minus sign but it doesn't show the calculate value!! Just shows zero with a minus or positive symbol depending on value.

This didn't work for me. I tried switching it to a text field and it still didn't work. I'm wondering if it has anything to do with the values being calculated instead of user inputting data. Oh well. Not a huge deal, just curious.

Is there a way to display the positive (plus) sign when a calculation result is positive?
