Testing for the presence of text in a range of cells

I need to test for the presence of text in a range of cells.
I have the following formula:
=IF(B289="",0,SUM(AA244+1))
Which works. B289 may or may not contain text. However, I want to return a zero if there is nothing in B289 through F308. I tried:
=IF(B289..F308="",0,SUM(AA244+1))  And got an error!
What am I doing wrong?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi,

You can try:
=IF((SUMPRODUCT(--(B289:F308<>""))=0)=TRUE,0,AA244+1)
