Multiple Sum Ifs by month

Hi All,
Some of you may recall I had this problem with quarterly data recently.
i thought I'd be able to copy it monthly but no such luck - please help I'm not sure what i am doing wrong?

I have some criteria within my data entry (Budget Entry) tab and I'd like to sum all of the totals.
If the subproject code (7 digits) begins with 230 or 280 AND the month is 4 I'd like all entries to sum under April.
or quarterly data I was using Sumproduct and then a ROUNDUP/3 function to get teh data to display in quarters - this works perfectly, but it is not transferrably to months - should i use SUMIFS?

For quarters I am using:
SUMPRODUCT('Budget Entry'!$Q$2:$Q$200*((LEFT('Budget Entry'!$F$2:$F$200,3)="230")+(LEFT('Budget Entry'!$F$2:$F$200,3)="280"))*(ROUNDUP('Budget Entry'!$N$2:$N$200/3,0)=COLUMNS($H7:I7)))
