Windows in object library not working

[Anonymous]

So every time I try to change any of the parameters on the windows in my ArchiCAD 10 object library, I get the message "Group operation error at line 870 in the 3D sript of file wa_trim_us_10.gsm" If I click continue, I can make the change, but this message pops up every time! Then, when I try to view the window in 3D after inputting it into my project, I get the message "Library part was not converted properly (W03)".

Can anyone help me fix this?

If you wall is 8" or smaller you will need to select the window/s.
Change the "Wall Type" to Stud wall OR change how far the window is set back in the wall.

Always set the wall type and the reveal size before placing a window/door.

The Reveal Size is what sets the window back in the wall.
