Cancelling the "Prompt user for input" tool

[tbob]

I have LV7.1 also, and after you put your fix, I can Cancel without filling in the text box also. After digging into the code, it is written so that an empty serial number string will not cause an exit loop if OK is clicked. I mistakingly thought it had something to do with the express vi.

Yup, seems to be true that linking the "cancel" to the stop button for the while loop lets me exit without needing to enter any text. At the bottom of the "Prompt User for Input" help screen it linked to another help screen for "Two Button Dialog" and that's where I found the info that helped explain it all.

Thanks again!
