Motors don't work in sync?

Ok so essentially all four of our motors work but the problem is, the left side wheels will run forward while the right side run backward, and vice versa, so all the robot does is go in circles. I'm sure it's a stupid/small mistake but here's what I've got.

Software solution: Invert the motors on one side

Hardware solution: reverse the motor wires for each motor on one side*


*NOT the wires coming from the battery to the motor controller

What he said.
The Motor Open has an Invert node on the bottom.

Awesome, thank you both! I won't be able to test until tomorrow but I'm gonna take your word that this will work:D I'll update if it does! Thanks again!
