if lineNum = 0 then
put 0 into someScroll
else if lineNum is a number then
put the effective textheight of fieldObject into lineHeight
put ((lineNum - 1) * lineHeight) * the height of fieldObject
into
someScroll
end if
set the scroll of fieldObject to someScroll
end field_ScrollToLine

David,
Could it be that the fixedLineHeight is off? That would mess up a
handler like this if there were varying sizes of text in the field.
As an alternative, I have simply used 'select line lineNum' in list
fields and the engine will automatically scroll to that line.
