nested array - Inconsistent units??

[Martin P]

I am struggling with this family?

I want to make the window units size correctly depending on the number of units, and the width...

Basically (if anyone cares to look!) I want to add the paramater "info 3" (an integer) in place of the 38 in my window unit width parameter (a length)

I cant see how to get round this??


info 3 = (number of units - 1) * 50 / number of units
window unit width = (width / number of units) + 38 mm


DUHHH!!! I got it.... whent I set up "info 3" I have to choose "length" as a paramater not "integer".... and I CAN now use "number of units" without getting an error message - even though it still seems to me like inconsistent units just done the other way round??
