Cant make player move

I have been trying to make the player move for ages, and neither me or my friends know how to fix the problem. We are all new to programming and very new to C#. Ill put the game as a file with the thread.
I followed this tuturial when I tried to make movement with Jetbrains Rider. (

)
(btw I lost my last save, but it didnt work there either.)

ok so I cant upload the whole project, but these two scripts sets my game on pause and I cant unpause. When I disable the scripts everything works, except from movement.

 

I don't have experience about scripting well yet, because I don't have monodevelop or visual studio. But I learned many online unity scripting tutorials. Now I understand about many basic words for scripting.
I think you would set,
float horizontalMove = 0f;
That 0f as 1f. (PlayerMovement.cs)
If it dosen't works, so sorry I can't help yet. reset it again.
Except, more information would be needed about your game to solve this.

 

Thank you, but that didnt work.,
I didnt figure out how to share the game, so I just shared the scripts, the problem is not that the player isnt walking, the problem is that it wont run with the script. The pause butten is paused when I try to play, and it cant be unpaused.
