I'm trying to use VLOOKUP to enter a grade point value based on a letter grade, then multiply it by the credit weight of a class (in an adjacent cell), BUT I just want a blank cell returned if there is no value, so the empty cells don't mess up a SUM formula that's also going on.
...works fine to take the letter grade in L5, look it up in the "Points" titled range and return the value, then multiply it by the credits in J5. But as soon as I try to wrap it all in an IFERROR function, it tells me I have too few arguments:
I was trying to follow this method. Should I be trying IF(ISNA)?
Thanks!
