Maybe this will get you started:
both of these scripts use "me" so they need to be placed inside the field script
-- show or hide a vert scrollbar
-- this could be triggered from several events
-- as an example, it is placed in the rawKeyDown handler
command ShowHideScrollBar
if (the formattedHeight of me)>(the height of me) then
set the vScrollBar of me to "true"
else
set the vScrollBar of me to "false"
end if
end ShowHideScrollBar
-- use the mouseWheel
on rawKeyDown theKeyNumber
ShowHideScrollBar
if theKeyNumber is 65308 then put 15 into tScrollInc -- increaseScroll -- mouse wheel down
if theKeyNumber is 65309 then put -15 into tScrollInc -- decreaseScroll -- mouse wheel up
if tScrollInc is empty then pass rawKeyDown -- don't forget this!
set the vScroll of me to (the vScroll of me + tScrollInc)
end rawKeyDown
