That works fine for me in Quark 7.5. BTW Witcher, you need to post in Firefox here - Safari swallows up your line endings! (or put them in manually via html)
Will test Q6....
No, it works perfectly in Quark 6 too.
HOWEVER, your error message does not match your script. If you are really asking for 'height of bounds of table box 1 of document 1 whose selected = true' it WILL error because you've already specified 'table box 1'.
In the script you just say 'first table box whose selected is true', and that works fine.
