you can do:

<when I recieve [go through]>
add (Other Variable) to [list]

I am just a little bit confused...

I'm trying to make a game, and there's a list called colors and, i need it to go through itself again. I'll upload it.

Use:

when I receive [gothrough v]
set [i v] to [1]
repeat (length of [colors v])
do stuff
change [i v] by [1]
end

Or:

when I receive [gobackthrough v]
set [i v] to (length of [colors v])
repeat (i)
do stuff
change [i v] by [-1]
end

If you want to reverse the order of the items in a list, use this:

when I receive [reverse v]
set [i v] to (length of [colors v])
repeat (i)
add (item (i) of [colors v] ) to [templist v]
change [i v] by [-1]
end
set [i v] to [1]
repeat (length of [templist v])
replace item (i) of [colors v] with (item (i) of [templist v])
change [i v] by [1]
end
delete (all v) of [templist v]

It should work...

What exactly do you want the script to do?

Like this?

When I Receive [render]
set [i] to (1)
go to x:(180) y:(-240)
repeat(24)
repeat(18)
switch to costume (item (i) of [list])
stamp
change x by (20)
change [i] by (1)
end
set x to (-240)
change y by (-20)
end

Cloning is currently impossible in Scratch (at least, without "hacking").  I'm still not sure what "going through itself" means.

Like this?

When I Receive [draw]
set [i] to (0)
repeat(length of [list])
change [i] by (1)
if<(item (i) of [list]) = [red]>
set pen color to [red]
else
if<(item (i) of [list]) = [blue]>
set pen color to [blue]
else
if<(item (i) of [list]) = [green]>
set pen color to [green]
end
end
end
draw stuff
end

You can't select color based off of variables directly in Scratch (I believe you can in Panther though).  A more efficient approach than the if-else statements may be to use the block:

set pen color to (item (i) of [list])

For this one, you can't put a () block in a color.

There are two "set pen color to" blocks.  One accepts "round" blocks and the other is the color square.  For the color square one (first one mentioned above), you need to use if-else statements and manually set the color.  For the second one, you can change the color by setting it to a variable's number.

Also, when I said "set color to [green]", that was using the color-square-block.  I don't know how to put in actual colors with the scratch blocks 

oh ok!

I tried using MoreGamesNow's script with his/her's block
Here is the result http://scratch.mit.edu/projects/coolhogs/2355713 It won't work. Can anyone fix it for me?

Thanks, I had to change some things!
