I have narrowed it down further:
Expr1: Format(Sum([city wide]+[pol]+[urban f]+[rural f]+[urban t]+[rural t]+[para t]+[education$]+[fir s]),"Currency")
Whatever is the second to be added in this formula can't be formatted, so in this example if I format [pol] to currency the formula won't work but if I leave it as non-formatted it will work fine, doesn't matter what I do it always get stuck on the second one if it is formatted?
