malformed expression word

[CrazyCat]

hi there

I've a trouble with a call to a procedure.

the code is (in a proc):
dbup $nick $handle $chan

and after I've:
proc dbup { user uhand uchan } {
...
}

when the procedure is called, even by the tcl or using in party-line the .tcl dbup me me #channel , I get the message "TCL error: malformed expression word"

I can't find what is wrong in this call.

thx helping me
