Hi,

It;s an array so when you copy the formula commit it by pressing
Ctrl+Shift+Enter

I used an "IF" function to make a column Q of "y" and "n" entries, as such:

=IF(P30,"Y","N")

I then used the following function:

=IF(Lines!$Q$3:$Q$57="n",SUMIF(Lines!$I$3:$I$57,"= 0",Lines!$F$3:$F$57),0)

i repeated the function for "y":

=IF(Lines!$Q$3:$Q$57="y",SUMIF(Lines!$I$3:$I$57,"= 0",Lines!$F$3:$F$57),0)

For some reason it will calculate the first formula, but not the second when
i paste it to another column. i
don't understand why it works for one and not the other...any ideas?
