I am trying to submit the form to add a mod vehicle. when I try to submit, it says that my 7z file name doesn't match my mod name, and it does. I don't if I'm doing something wrong. Please help haha

I want to create a modified FZR with improved weight distribution, wider tires, AWD, and best of all more power. This is my first mod and I just want to use it to have fun in cruise servers. I'm having a hard time figuring out this submission form. any help would be awesome!!
