How to prevent a lookup to run if a field is empty

[guscastro]

Hello.
I want to stop a lookup if a field is empty.

This is what I've done so far

1. I added and onclick Event to the lookup bottom :

ONCLICK EVENT
nuSetHash('bob', 'world');
nuRunPHP( 'myphpcode', 'my_iframe_on_quotes');

'myphpcode' PHP code looks like:
if ( '#field1#' == '' ) { die() ; }

my_iframe_on_quotes is and Iframe on a form call quotes where the lookup is placed.
field1 is the field in the form I want to

I was expecting that die() php function would stop the execution of the look up, but it didn't
I would appreciate your help on this regards.
