Change sheetmetal thickness

Hi, all. New member here, with my 1st question:
I have a decent amount of experience with SW sheet metal, but I don't often start things with the Base Flange feature, and when I have, I've never had to later change the sheet metal thickness. But it doesn't appear possible to change the sheet metal thickness of a part started with Base Flange after the fact. I started out with a box with .06 thickness, but as the design has evolved, the box is much bigger now, and I want to change its thickness to .09, but the thickness value is disabled (grayed out) in the Sheet Metal feature now. Rolling back doesn't work (but why shouldn't it?)and I can't change it in Equations. The help file is helpless (for this, it seems, anyway). This has to be something simple that I'm missing - I will resist shooting myself when I get the answer

Which version of SW?

Are you trying to change the thickness within the top level Sheet-Metal feature, or the Sheet-Metal2 (or subsequent) feature?

If in one of the subsequent features, make sure the Override default parameters option is selected.

OK, Never Mind - found my brain hiding under my desk, popped it back in, and figured it out. Of course it was obvious & simple enough. Well, not that obvious at 1st - had to refresh my memory on how a linked value might get initially created when the user doesn't actually do the work of creating the link. Modifying the Base Flange affords you the opportunity to change its thickness dimension, which is the linked value.
