This seems to work, although the line only moves in real time with the thumb of scroll bar 1, when I move the thumb of scrollbar 2 the line only moves (jumps) into position on mouseUp

Sorted it, just applied

Nicely done.

Can you rewrite this using a repeat loop that finds each thumbposition of the 20 and sets the points accordingly? That way the whole shebang can be done in a handful of lines of code.

Look up the "repeat with counter = startValue [to | down to] endValue" form of the repeat control structure. I know you can do this.
