Nextbot NPC Not Looping Walk Animation

So I’ve got this Nextbot NPC I’ve been working on. It follows the player and plays walking animations. But they don’t loop. Here is my code.
[lua]
self:SetSequence(“my run sequence here”,1)
self:SetPlaybackRate(1)
[/lua]

But before I used the code above, I was using the below
[lua]
self:StartActivity( ACT_MP_RUN_MELEE,2 )
self:SetPlaybackRate(2)
[/lua]
The reason I changed was because the bit of code about this text played the animations slowly. I messed with the Rate and the number beside the animation without any luck.
So the question is, how do I loop the animation for the top code, or how do I change the speed properly of the bottom code. Either answer should do.

EDIT: Fixed, change the sequence to
[lua]
self:StartActivity( ACT_MP_RUN_MELEE,2 )
self:SetPlaybackRate(1)
[/lua]
