little arrows Increase/decrease a field value

[rev at armbase.com]

Hi All

i've searched the docs on the little arrows (in the tools). I wanty to increase
the numeric value of a field using the little arrows at the side

It seems that they are Scrollbars and A search for scrollbars says use something
like this.
on scrollbarLineDec
  Put field ButtonWidth into tBtnWidth
  put (BtnWidth + 1) into BtnWidth
  Put BtnWidth into field ButtonWidth
end scrollbarLineDec

on scrollbarLineInc
    Put field ButtonWidth into tBtnWidth
  put (BtnWidth -1) into BtnWidth
  Put BtnWidth into field ButtonWidth
end scrollbarLineInc

These both fail (when the () are removed the don't work either)

I would have thought that something as simple as this and in the tools would
have a section in the docs?

Heeeelp. :-)

Cheers
Bob
