Countif in VBA

[Information Hog]

I have several worksheets that are set up the same. I need a sub or function that will count numbers in cells and put the count in a cell . I tried

=countif(b8:bj19,"2")+countif(b8:bj19,"3")+countif(b8:bj19,"4")

works fine, but I need it to look at every other row

Example (b8:b19,d8:d19,f8:f19...bj8:bj19) 31 ranges

The criteria would be the same. Also, is it possible to have the macro start when you double click a cell and have the macro check that cell on every worksheet for the same countif statement? If so, how?

Thanks, In advance for the help.

Is there another way to do the same thing?
