I got a column with several rows containing `m`

or `w`

.

So I just want to count how many of that rows contain the letter `w`

. This looks like a rather simple task but excel is throwing an error on me when I use the function like this:

`=COUNTIF(C2:C123, "w")`

There`s a problem with this forlmula When the first character is an equal (=) or minus (-) sign, Excel thinks it's a formula

I looked at the documentation of the formula:

It seems that I'm doing nothing wrong here. What is causing this type of error?
