Try this instead
=IF(COUNT(AT17,AU17,AV17,AW17,AX17,AY17,AZ17,BA17, BB17,BC17,BD17,BE171,SUM(AT17:BE17),"")

or

=IF(SUM(AT17:BE17)0,sum(AT17:BE17),"")

Hi,
Part of my spreadsheet has twelve columns, one for each month. To the right
of this, is a column for the yearly total. I am trying to use a formula that
will total up the sums across a row for each month. The problem is that if
there is nothing entered into the monthly columns, then i don't want the
total column to show zeros as this looks messy and may confuse some of the
clerks who will be using this spreadsheet and have minimal excel training. I
had posed this question here before and been told to use the
"=IF(COUNT(AT17,AU17,AV17,AW17,AX17,AY17,AZ17,BA17 ,BB17,BC17,BD17,BE17)=1,SUM(AT17:BE17),"")"
formula. This seemed to work well....until i entered values in for more than
one of the months. When i do that, the total column just stays blank instead
of adding up the monthly totals. Please help!

Thanks. Shannan.
