Question : sumproduct formula help

Good Afternoon,
I need some help with a sumproduct formula.  I have one tab (input tab) cell A1 where I would enter in the 4 digit number and then it would return monthly data from the data tab.  Not sure how to write the sumproduct formula.  I have attached the file for reference.

Answer : sumproduct formula help

hi
one way to do it to use index and match formulae

Put this formula in cell C5 of your Input sheet
=INDEX(data!$B$5:$M$154,MATCH(INPUT!$A$1,data!$A$5:$A$154,0),MATCH(INPUT!$A5,data!$B$4:$M$4,0))

pull it down to get your values.

hope this helps.
