Bag mod won't resize correctly by number of slots

[ger]

Okay folks, time to show my XML ignorance. Got a request for a 3/4 version of my no-overlap with grab-handle and started working to fill it, but I've run into a problem and I can't figure out what it is.

When I set the page scrollextent/size to what should be the maximum possible bag size (assuming a 20 slot bag) it crops part of the last line of a 12 slot bag. When I tweak scrollextent and size so that a 12 slot bag displays correctly it crops part of the bottom row of a 6 slot bag. I can't for the life of me figure out what I've done wrong, but I'm hopinh you guys and gals can. Code to follow.
