If Field In application is blank Write text. Topic is solved

[cleadus_fetus]

I have an application that I need to fill out a password field on a certain tab for many entries in a list.
I have it set so when I press my hotkey it pastes the password. Presses enter for OK. goes down to the next entry and opens it.
It navigates its way to the proper TAB and then field.
at which point I would press the hotkey again.

I need to do this on several different boxes and the list length is not the same on each.

Is there a way to have autohotkey test if the password field is empty. if it is write my text and move on to the next target (keep looping the script). but if the field is not empty to end the script.
