I need a formula for looking for a specific word in the same column on all tabs,i know how to do the formula for 1 tab 
=SUMPRODUCT((FEB!$A$15:$A$1000=SUMMARY!A4)*(FEB!$F$15:$F$1000=FEB!$AF$3))
but over muliple tabs i have to repeat it for each tab. Example 
=SUMPRODUCT((FEB!$A$15:$A$1000=SUMMARY!A6)*(FEB!$F$15:$F$1000=FEB!$AF$3))+SUMPRODUCT((MAR!$A$15:$A$1000=SUMMARY!A6)*(MAR!$F$15:$F$1000=FEB!$AF$3))+SUMPRODUCT((APR!$A$15:$A$1000=SUMMARY!A6)*(APR!$F$15:$F$1000=FEB!$AF$3))
The must be an easier way.

Thanks
