TRUE or FALSE for a range of numbers

I am trying to come up with a formula that will search an array let's say B9:AE9 (which contain numbers) and check to see if every cell is over 30. If it is I want to return TRUE, If even one of the cells is below 30 I want it to say false. Any ideas?

Try

=MIN(B9:AE9)>=30

Jonmo that worked great. How about now if some of the cells are blank. How can I disregard those ones?

Try

=COUNTIF(B9:AE9,"<30")=0

You are brilliant Jonmo. Thanks.

Glad to help.
