Syntax error

If what you did was remove the ", ", then you did not follow what I posted. That is not what I did. Look more closely at the difference between what you had and what I changed it to.

It may still have another problem that I did not see but hopefully fixing this one will do it.

It is in this piece of the formula.

Instead of C21="Print - Screen, "165 degrees", ",

should be C21="Print - Screen", "165 degrees",

You do not need the IFERROR if you add to the IFS a final ifs-expression of TRUE and final ifs-true of "" . It becomes the result if none of the other conditions are met and there will be no error to catch.
