What I am trying to achieve is to see if the value of Cell C4 exists in Column F.
If it exists in Column F, I eventually want Cell A4 to copy the format of the cell in Column F that matches the value of Cell C4.
Still following me?
For reference, my file looks like this:

The values of the cells in Column A are based on Sheet2.
So with a simple formula I managed to compare the values and only change Column A when there is an actual match as seen below.
=IF(C4=F:F, IF(C4<>"","x",Sheet2!A4), Sheet2!A4)
The only problem here is that it only results in a TRUE statement, if Cell C4 matches Cell F4. If it matches, let's say Cell F5, the statement will be FALSE and I need it to be TRUE (since value of C4 is indeed found in Column F.
I tried a variation using $F:$F instead of F:F, but this made no difference. Also setting a range (F2:F5) did not work.
This is where I am stuck.
As soon as I have this figured out, I can continue finding a way of copying the format of the matched cell. Feel free to reveal how I manage to do this if you already know. Will save me some headaches.
