Scratch

I'm not sure if this should be in help with scripts or bugs and glitches as I'm not sure if it's a problem with scratch or with my code. If it's misplaced, please report it to be moved.
I'm working on implementing a programming language in scratch. I decided to write some debugging scripts to help me test weather what I've got so far is working. However, It won't work. I traced the problem to this script:

when I receive [ready v]

forever  

delete (all v) of [command v]

ask [Next command] and wait

set [word v] to []

set [index v] to [0]

repeat (length of (answer))  

change [index v] by (1)

if <(letter (index) of (answer)) = [ ]> // that's a space by the way

add (word) to [command v]

set [word v] to []

else

set [word v] to (join (word) (letter (index) of (answer)))

end

end

add (word) to [command v]

broadcast (join [TEST do command ] (item (1 v) of [command v] )) and wait

end

I typed in "say 3", which is supposed to, er, say the number 3. However, It appears to ignore the command and continue. (it appears to ignore ALL commands and continue) I tried it in single stepping mode, and found the broadcast block isn't running the join block. The script that had the hat block

 when I receive [TEST do command say v]

didn't flash white. I have no idea what it DID broadcast. It is times like this when I wish scratch had a (most recent broadcast) block. Are you meant to put reporters in the broadcast block? If you are, scratch should evaluate it properly. If you're not, scratch should not make it possible.

Can someone tell me what's wrong???
