Why Can’t I Use the “Count” Parameter in my Schedule Formulas?

January 19, 2011

Seems like a logical question.  The parameter is counting the items now I just want to use that value in my formula.  But wait Revit says you can’t!

Here’s a explanation of how to get around this idiosyncrasy.  With a completely counter intuitive process. 

Essentially you need to create a calculated value parameter, called let’s say “Total” that points to a parameter in your schedule that contains the value you want to multiple the count by and once the parameter is created you check the “Calculate Totals” box in the Schedule Properties “Formatting” tab for that “Total” parameter.

If that doesn’t explain it try this Link.

  1. I’ve been doing this for years. The one trick most people don’t understand is it works best when scheduling by type (not instance). Also, set your new “count” parameter as “1” in the formula field. This will make it hard to change (which is what you want!) when in the project.
