Count number of time it appears in the data list

Hi, I have a sheet with a list of potential buyer who have viewed the car. What formula should I used to count the number of times a potential buyer has viewedthe vehicle during a specific month and year and the number of view will be reflected on another sheet? I have tried using sumproduct but I'm having error. I am unsure if I have used the formula wrongly.

Hope to seek some advice on this.

Thank You

Thanks FDibbins and Crooza for the prompt reply. I have tried both formula using the steps given however, the results dosent tally with the Statistics

And here's the file. As I said above it looks right to me but let me know where you expected difference

Edit - I also just checked Ford's solution and we're getting the same results

Crooza, apologise, I accidentally press onto one letter that's wht it's not tally. Apologise for my mistake..

Thanks FDibbins, your formula works as well..
