Nextbot NPC Not Looping Walk Animation

[ErrolLiamP]

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]
