cannot solve with countif function

[sanlen]

Hi,

I am trying to use countif function to count value in columnA1:A11 and the condition would be base on columnB1:B11=cellE1. I am trying with this =COUNTIF(A1:A11,B1:B11=E1).

could you please advice if i am on the right way? i also would like to solve this with sumproduct, would it work?

I have attached a worksheet along. Thanks you very much for your time and all the comments you may give me.
