Equation w/ driven dimension

[JHT82]

I have a driven dimension d288 and would like to make an equation with it, with a user parameter.

For some reason it won't let me...

My user paratemer (qty) is 1200mm and my driven is (2600mm)

I would like the eqaution to be:

round(d288/qty)

Am I doing somehting wrong, or is it just not possible?

Attach sample file here.

Problems like this are almost always the result of not properly accounting for unit cancellation.

With pencil and paper - write out your equation including the units.  Have you accounted for the units?

You might try using Floor or Ceiling instead of Round, or try to remove the units.
