Trying to calculate # of times text string is displayed
 

I have a worksheet where I track what I've applied the number to; i.e. acct #
in column A and user type in column E (nanny, sitter). I'd like to use a
function to calculate how many rows are classified as "nanny" or "sitter".

The outcome I'm looking for is the same as if I go Ctrl+F, "Nanny", Find All
which gives me 66 right now. But rather than having to do this manually, I'd
like a running total.

The data is in rows 2 to 133, columns A to E, but I only need column E to
calculate.

I can provide more info if needed, I just don't know how to find what I'm
looking for. Thanks for any help!
