# Conditional Sum over many worksheets problem

#### XL Learner

Hello,

I am trying to conditionally sum numbers over 52 worksheets based upon up to 3 conditions. One condition is a date, the other condition is a company name. Right now I am using only 2 conditions but may add a third.

I am using an array formula to get the result I need for that worksheet. Here it is:
{=SUM((I4:M4=V5)*(F6:F42=V4)*I6:M42)}

My question is this.....How do I get the results I need for all 52 worksheets in one formula?

All information on all worksheets are in the exact same cell references.

My goal is to have a reporting worksheet that has all 365 days of the year and depending on what company is is in the first cell; all dates have the respective number that for that day that is contained on another worksheet.

I know my description is a little vuage, if I need to clarify, please let me know.

### Excel Facts

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.

Excel contains over 450 functions, with more added every year. That’s a huge number, so where should you start? Right here with this bundle.
