Alright, thanks for the help.
And CallieJo2, I believe you need to find that SQL statement and get rid of the dash just before the WHERE. Either that or you're missing a number after the dash, and it's looking for the rest of the arithmetic statement and not finding it. Someone who knows how the code works would know.
This might help you:
