SUMPRODUCT formula:pretty simple formulae

I have a pretty simple formulae that matches a code in "Jan Timesheets" tab, column A against the code in the "Summary" tab, column A and totals the values for this match in timesheets column V, this reads as follows:

=SUMIF('Jan Timesheets'!A:A,Summary!A14,'Jan Timesheets'!V:V)

What i now want to do is bring this data across but not only matching code in Timesheets AA, but match with Timesheets AA and B:B equals 0100?

Any help much appreciated, i'm still leaning formulaes as you can probably tell ...
