Problem with Enemies (Platformer Module)

I am trying to get a simple enemy working with the Platformer Module.

I just want it to move randomly left and right.

Followed the adventure and Platformer tutorials, but my enemies just sit in 1 spot. The only way to move them is to attack them.

I do have the behaviors set:
Action LR movement
At solid Reverse Direction
At edge Reverse Direction

You set your monster speed and acceleration, right?!

...
Well I certainly feel dumb now. I wondered why nobody else was experiencing the problem.

Thats what I get for trying to work on something at midnight lol.

Thanks for helping me out despite it being a dumb question lol.

I actually HAD set a speed, but forgot to set acceleration.

Yeah, don't worry. Aha, we all made that mistake... at a certain point
