using arrays to make code work when bot is on many channels

[z_one]

I have the following code:

bind join - * betaz
proc betaz {nick uhost hand chan} {
global ipjoinlast

set ipjoinbmask *!*[string tolower [string range $uhost [string first "@" $uhost] end]]

if {$ipjoinlast($chan) != ""} {
set ipjoinlast($chan) "0.0.0.0"
}
...

and when I run it on channel #mychan I get the following error msg, why ?

TCL error [betaz]: can't set "ipjoinlast(#mychan)": variable isn't array

[ppslim]

bind join - * betaz
proc betaz {nick uhost hand chan} {
global ipjoinlast

set ipjoinbmask($chan) *!*[string tolower [string range $uhost [string first "@" $uhost] end]]
}

Note that you where using 2 set commands on the same var name, but of 2 different types, which is the reason for the error.

I'm sorry I typed the following line wrong:

set ipjoinbmask *!*[string tolower [string range $uhost [string first "@" $uhost] end]]

actually I used this in my code (using and array to make the variable channel specific too)

set ipjoinbmask($chan) *!*[string tolower [string range $uhost [string first "@" $uhost] end]]

Which variable am I setting twice ?
I have:

set ipjoinbmask($chan)

set ipjoinlast($chan)

They are two different variables.
I'm sorry I didn't get ur last point, if there's anything I missed pls feel free to explain

Thanks in advance

Perhaps I should rephrase to help u guys see what I mean
I read an article that specifies that the global command converts entire arrays, not just individual strings:
http://www.suninet.nl/tclguide/tclguide-ch5.html#ch5.5

Why then when I initialize as follows:

proc betaz {nick uhost hand chan} {
global ipjoinlast
if (![info exists ipjoinlast($chan)]) {
set ipjoinlast($chan) ""
}
...
}

I get the following error:

TCL error [betaz]: can't set "ipjoinlast(#mychannel)": variable isn't array

You must have already set the variable somewhere else (perhaps initialization). Once you set a variable, it can no longer be an array. Just get rid of that part and it should work.
