Multiply Schedule field values

[Spork]

Hi all,

I have created a schedule of some parameters of a custom family that I made. Among those are Length and Width. Instead of creating a field for Area, which gives me the total surface area of my object, I just want the Width X Length. I attempted to create a Calculated Value, which was Width*Length, but I get this error: "The following is not a valid schedule field: Width", even though I selected it from the list of available fields by clicking on the box with 3 dots. Anyone come across this, or know a workaround? Does it have something to do with it being a shared parameter from the family I created?

Thanks,
JP

Can you post a screencap of the dialog which is producing this error and/or attach your family file here?

The problem is that you used a "-" in the parameter name. Revit interprets that as "Width" MINUS "Shared", hence the error. You will have to use a different parameter name; either omit the "-" or use a special dash from the Character Map (such as "En Dash", alt+0150).

And here's my file.

Ok, that's good to know. These are shared parameters, and going into the editing feature I can't seem to rename it. If I delete it and create a new one I will have to re-do all my families. Am I missing something?

Unfortunately, I don't think you are missing anything - you cannot simply rename a Shared Parameter. However, there may be a way I don't know of (such as a parameter add-in) so search the forums and perhaps you'll find something. Good luck!

I just made a new one without the dash, it wasn't too hard to switch. It works!

I still can't get those fields to calculate totals, though.

Duplicate post, sorry

Do you mean displaying a total Area for that entire Field?
