Solved Setting sign text

[Remixful]

Hello everyone. I'm new to Skripting.

So, I'm trying to figure out a way of creating a sign and setting the text of it.

This is my first attempt.

set {_sign} to sign
set line 1 of {_sign} to "test"
send "%line 1 of {_sign}%"

it prints <none> which really frustrates me. (and of course the sign is blank if i try to place it)

So next attempt:

on place of furnace:
    set block in front of event-block to wall_sign
    set line 1 of block in front of event-block to "this is line 1"
    set line 2 of block in front of event-block to "this is line 2"

I hate being repetitive. I don't want to use "block in front of event-block" more than once, it really bothers me.
Is there a way to reference the wall_sign I created?

Thanks in advance.

on place of furnace:
    set block in front of event-block to wall_sign
    set {_sign} to block in front of event-block
    set line 1 of {_sign} to "this is line 1"
    set line 2 of {_sign} to "this is line 2"

I found the solution. Variable and object referencing is very confusing.
