Linking dimension parameters in schedule

[fangirlsims]

Right now some dimensions "door panel thickness"  etc. of a certain door are missing from the schedule.

I tried adding a "panel thickness" parameter to that door

but I can't figure out how to link that parameter to the "door panel thickness" parameter in the schedule

You'll need to use shared parameters. There are plenty of online resources that explain how to use them. I'd recommend doing some quick research and then coming back here if you have specific questions.
