Error In Vehicle/Object

Hello, im brand new to modding in BeamNG and I decided to follow the content creation tutorial on how to make a tug. I followed all the steps but when I went to load it up in beam it says "Error in vehicle/object" and "Failed to load".

I cant work out how to fix it so im hoping someone could help cheers

 

I get the same message.

Hmmm...

If I figure it out (I probably won't) I'll tell you

 

Cheers, good luck
