"Parameter sText to function SetText is NULL" error occurs when checking the present text in the text box.
How can I get rid of this problem?
Why are you using SetText() instead of GetText() or VerifyValue()
Have you ever noticed? Anybody going slower than you is an idiot, and anyone going faster than you is a maniac.
Sounds like you are using a data driven test to set the text before you check it?
If so, put a single quote ' in the spreadsheet, rather than leaving it blank
