There’s probably a way to make this work using
ROUNDUP(), but having been an English major, I took the low road and did it this way:
Essentially, it checks to see if the calculated amount is evenly divisible by
1.5. If it is, fine; if not, it takes the integer quotient, adds
1, and multiplies the result by
1.5. I tossed a few numbers at it, and it seemed to work — but because of the way Discourse (the software running this forum) interpreted your embedded '
*'s, I had to guess at your formula and field names, so you’ll want to double-check my work.
