[Javascript] confusing ....

[Andreas Krite]

Hiya,

I'm not really new to this list and hope that someone could help me finding the right way.
I like to build a mail-form where you can choose via drop-down a recipient 1 and a recipient 2 - the example listed below is not working :-(( and I'm not experienced enough to find the error.

Thanks in advance

regards
Andreas
