Formula: =COUNTIFS(B:B,"AS2",D:D,"MCT")

In column E (Total amount) - I have dollar values. I want to count all the
cells in this column that has a "$" sign. Or... I want the formula to
subtract any blank cells in this column so that it gives me a total number.
I've tried to use: =COUNTIFS(B:B,"AS2",D:D,"MCT",E:E,"$") - RESULT: "0"
(Which is incorrect)
