using more then one $something

[GodForsakenSoul]

i'm kinda bored so i'm practicing my autoit skills. now here's a little problem i'm having:

dim $1
dim $2
dim $3
dim $4 

code code code
code code code
code code code

msgbox (1, "", $1 $2 $3 $4)

this doesn't work. the compiler thing says that the last line is the thing to blame.

i'd like to know how i can solve this.

also, i'm going to substitute the last line to

send ("{ASC $1$2$3$4})[/code

and i'd like to know if the solution purposed with the msgbox thing can be used with this to this line aswell.

i TRIED making it one dim thing but it didn't work as well as i hoped.
