So I watched a tutorial
About how to make
Platformer but
When I am trying to make
Wall jumping
It works
But I want it to jump
Further not stay on wall
I followed the tutorial
But his script didn't work!
Can anyone help me
Fix the script?

Not sure I understand the question. Do you mean jump higher when not touching the wall? So you don't need to be touchng anything to jump?

theres three reasons it could not be working… either your watching a video on a scratch that very old, you did'nt follow all his instructions well enough, or what i think is happining, your script is based off of whether he touches the wall. to fix this just have him move further away from the wall until you know for sure hes not touching. is the wall stopping movement when touched?

when green flag clicked
repeat until < you figure out why your project isn't working>
bang your head on your desk for hours,  fiddle your thumbs and play with a paper clip to pass the time, 
have a staring contest with the broken code, envy every coder who's better than you, repeat (for 2 weeks) procrastinate
