SUMIF Not Working
I'm needing to sum of all accounts that begin with R.. I'm using this formula. Is there a different way to sum up the cost for these accounts?
=SUMIF([TSA ID #]6:[TSA ID #]206, "R.*", Monthly6:Monthly206)
Answers

Below is presuming that you want to sum the amounts in the Monthly column and look for "R." in the TSA ID column:
=SUMIFS(Monthly6:Monthly206, [TSA ID #]6:[TSA ID #]206, LEFT(@cell, 1) = "R.")
