I have a formula to search a sheet for certain criteria and sum up the total, data is entered into this sheet by week number, where I then filter it for whichever week I need. I following formula works fine, but adds all the cells including hidden ones, how can i get it to ignore hidden cells??
=SUM(IF('FT Line 1-RX'!$C$2:$C$2100='FT costs 1-Rx'!B$1,IF('FT Line 1-RX'!$E$1:$GT$1='FT costs 1-Rx'!$A11,'FT Line 1-RX'!$E$2:$GT$2100)))
There is raw data in the 'FT Line 1-RX' sheet which is summed up in the 'FT costs 1-RX' sheet.
