Need HELP with verifying missing data

[Chubs]

I need some help figuring this out please.

I am writing a script to run on info provided in a GUI all fields need to be filled out for the script to work. I am trying to write in code to prompt with a list of missing info if left blank when you click the start button. I don't really want to use ini files. I can do this all day for just one variable but am having problems checking for multiple variables/inputs. Tried fooling around with "For" statement but either I am over thinking it or I am going about it all wrong. Can anyone help out with this please?

Hi bro, im not a pro, but, what info you want to feel in the inputs?!?!

I am looking for the tech to enter in his name, cu's id# and user datapath on server to be used later in the script and for logging purposes. If tech clicks start before entering all needed info, have script prompt the fields that were missed the go back to gui to be corrected....the script listed above is to show general idea method. There is alot of other fields on the gui but did not post them to keep the idea simple for the forums.
