Hi,

I have a small aplication with two inputTextFields and a button, when the button is pressed it triggers a function that calculates the value in the two text fields, and everything is fine but when the textFileds are empty which is the default value and the button is press I get an error (Error: Error #1502: A script has executed for longer than the default timeout period of 15 seconds.)

My question is how can I detect if the inputTextFileds are empty and some how kill the main function ?

function Name: calculate  
Input Text Field 1: partL\_txt  
Input Text Field 2: partW\_txt  
Button Name: enterBtn

Thanks a lot!
