Your formula is an ARRAY formula that when entered or edited must be
finished with ctrl+shift+enter instead of just enter. You said nothing about
formatting.

I have this formula in a cell: {=SUM(IF(ISTEXT(C6:Q6),1,0))}
When I press F2 and hit enter excel removes the brakets from the formula
and
instead of having the sum I got zero as a result.

How can I edit the formula without changing the format?

When I insert the brackets, excel treats the formula into a text value.

Thanks
