@Leno_Marin what does your formula look like? Can you post it here surrounded by three backticks on either side (```) so we can see what you have in the ROUNDUP()
function?
Are you making sure to provide a precision value to the function? If you want to round to a whole integer, like 4, you’ll want to provide 0
as the precision value:
ROUNDUP({Wall Width} / {Usable Role Width}, 0)
