Clicks on a visual analog scale

[Abramson, Anna]

Hello,
A couple of quick questions that maybe someone can offer some help on..
1. Does anyone know how to modify the visual analog mouse click setup so that a subject can click and unclick until he settles on one final choice??

2. Is there a way to have a selected box on a visual analog scale change so the subject can see his/her choice---ie, box is highlighted, Xed, changes color? I know how to do this on the Grid, but I cant seem to apply it to the visual mouse click.

3. Is it possible to have multiple rows where the subject must choose one box per row--so the program allows multiple clicks, one per row?

THANK YOU.
