Animations not playing on a custom rig?

I made a custom character rig, that is a fully jointed human body and everything is set up, i load in as the model just fine and i can move around but the only problem is that no animation plays, now walking animation or idle animation and i have made both. ive looked over the ROBLOX Wiki and none of that worked. i know you have to have a LocalScript in the Character model.

theres not really any code to paste here since its pretty much all from the Wiki.
