[Detect if an avatar has already touched an object?]

Thank you for the help.  Worked like a charm!

[Detect if an avatar has already touched an object?]

I've searched quite a bit for an answer on this already, but hopefully I can get someone's help on here.  Is there a way to detect if an avatar has already touched an object before?  I was hoping I could store the detected keys into a notecard and read each line to see if it matched the detected key, but it looks like writing to notecards can't be done through a script.  So, is there any alternative ways to accomplish this?

Thanks.
