Sumifs formula that will calculate the sum of multiple criteria

Hello,

Attached is a spreadsheet with 2 tabs at the bottom ("Solex" and "Summary"). In the Summary tab, I wrote a formula in Columns E:G that will sum up the Dollars of certain Columns in the Solex tabs that have the same Column Header Name that are in Columns E:G of the Summary tab. For example: One Name of the Column Header is "E-Regular - WK1" The problem with my formula is that it is column specific in the Solex Tab, meaning that if the Column changed from "W" to "X" then I would not get the sum of the data that I want it to sum. I hope I explained this properly. I'm still fairly new with excel so any help with rewriting these formulas would be appreciated.

Recap : Summary tab should have a formula that will sum the dollars based on the "Header Name" of the column on the Summary Tab, and then the "Store Name", and then the "Check Date."

Thank You in advance for any and all time spent on helping me with my issue.
