Too many SUMIFS = huge workbook. Help with what else to use? Index/Match?

Hi there,

Please can someone help me?

I have data stored in sheets where the cinema name populates column B, and the data is in columns from D onwards. Below this data, I have a SUMIF counting all the values that match ODEON (for example) then go to column D and sum the data for ODEON.

Problem is, the worksheet will grow (more columns with subsequent weeks worth of data) and I will have 22 worksheets for 22 different screenings. I started to multiply the one attached and the file quickly grew to 4.5MB, and I wasn't even halfway done.

I am not familiar with pivot tables, so tried index/match. My attempts are in cells D390 toD392 before I screamed in frustration. I'm sure it's possible on a formula basis without pivots, just not able to get it to work.

Could anyone offer me an assist please?

All the best,

Ian
