Confirming Text in text entry fields.

Hi sorry, I meant the variable.

I have attached the problem slide here.   The 2 variables are-  Text Entry 2 and Text Entry 3 (not sure how I can change the name for this.

The other issue I have is-  Numeric Entry-   IT won't show a layer if the field is left blank.

I have figured out how to show layer when text entry field is blank, but not sure what to do for Numeric entry field.

Just some background info.  I work in a prison, so we don't have internet access, and I am trying to create a website simulation.   

I really appreciate any support you can give.

Thanks,
