Can't exchange values of variables. Trace returns "undefined"?

Hai,

I’m trying to pass the value of a variable in to another but tracing that value returns “undefined”

This is what i do:
1 Im loading the values from an external .txt file. in the .txt file it says…

&customer1=blahblah

2 A textfield in Flash with the var: value “customer1” shows the externally loaded value…blahblah. So this is good:D

3 When I try to pass the value “blahblah” to another variable it returns “undefined” ??

test = customer1;

Also tried:
test = eval(customer1);

I’m definitly doing something wrong here. can’t be that hard?!?
Can somebody help me?

Thanks,
Marc
