Countif formula with multiple criteria and a date range

Question

I have a spreadsheet where I am counting the number of occurrences where the words below occur during a date range: “Not Interested, Career Link, OVR, VBA, No Show”. All these are found in the same column, on Referrals" worksheet. I am trying to count the number of times that there is value in a cell other than the above. Is that possible? Below is an example of the formula that I am currently using to count :

=COUNTIFS(Referrals!$K$2:$K$306,"VBA",Referrals!$A$2:$A$306,"<11/1/15")

Referrals refer to the "Referrals" worksheet. "VBA" is located on Referrals worksheet, Column K.

Answer 1

The formula below counts the cells that do NOT contain the values “Not Interested, Career Link, OVR, VBA, No Show”

=COUNTIFS($K:$K,"<>Not Interested",$K:$K,"<>Career Link",$K:$K,"<>OVR",$K:$K,"<>VBA",$K:$K,"<>No Show",$A:$A,"<11/1/15")
