Sumifs with Conditions across multiple sheets using indirect.

[NexusP]

I created a formula that compares an existing list with names linked to total sessions selected from list on different sheets and once the criteria is matched the sessions are tallied in the formula cell. My initial formula would be to difficult for people to change and it's sluggish. I tried to use a more streamlined formula that uses a list pointing to =Data!$C:$C which contains Jan-Dec, and =Data!$C$1:$C$12 and =Data!$C1:$C12 but it only reads information from the first Sheet. I also tried numbers and that doesn't work either. I know that it is reading the sheet correctly because if i change the name, the results go to #REF!. Can anyone help with this issue?

Initial Formula

=SUMIFS(Jan!E:E,Jan!D:D,"="&B1,Jan!B:B,"=Hoyt")+SUMIFS(Feb!E:E,Feb!D:D,"="&B1,Feb!B:B,"=Hoyt")+SUMIFS(Mar!E:E,Mar!D:D,"="&B1,Mar!B:B,"=Hoyt")+SUMIFS(Apr!E:E,Apr!D:D,"="&B1,Apr!B:B,"=Hoyt")+SUMIFS(May!E:E,May!D:D,"="&B1,May!B:B,"=Hoyt")+SUMIFS(Jun!E:E,Jun!D:D,"="&B1,Jun!B:B,"=Hoyt")+SUMIFS(Jul!E:E,Jul!D:D,"="&B1,Jul!B:B,"=Hoyt")+SUMIFS(Aug!E:E,Aug!D:D,"="&B1,Aug!B:B,"=Hoyt")+SUMIFS(Sep!E:E,Sep!D:D,"="&B1,Sep!B:B,"=Hoyt")+SUMIFS(Oct!E:E,Oct!D:D,"="&B1,Oct!B:B,"=Hoyt")+SUMIFS(Nov!E:E,Nov!D:D,"="&B1,Nov!B:B,"=Hoyt")+SUMIFS(Dec!E:E,Dec!D:D,"="&B1,Dec!B:B,"=Hoyt")

Current Formula

=SUMIFS(INDIRECT("'"&Month&"'!E:E"),INDIRECT("'"&Month&"'!D:D"),"="&B1,INDIRECT("'"&Month&"'!B:B"),"=Hoyt")
