Hi Colin,
Realize I’m getting in the middle of this, but I usually try to work and understand most of the projects on the boards. Part of the problem is I guess I don’t know what effect I’m working to achieve, so…
Anyway, just from guessing, I set up a 5 second 640X480 comp, then put a photo on one layer, and applied the expression youd posted to the scale. It complained, so I made a 50X50 solid layer above just named “mouse layer”. The expression still complains, saying the results need to be of dimension 2, not 1. I reread your instructions several times, saying to pickwhip the layer for the mouse layer, but I guess I’m still not getting it… any suggestions, or perhaps even a link or desription to the effect?
Thanks in advance for your help, and I greatly appreciate you posting expressions. Although I’ve generated a few of my own, I typically modify ones I’ve seen that are cool, or simply use the pickwhip with the “built-ins”, as I’m definitely a student, and not a master!
