Animation Playing Troubles?

So, I've been having a problem with my animations, which are being used in tools. For example, if you're holding a weapon, I want my animations to override the default ROBLOX holding of a tool.

But obviously, that's not working out. Instead, it turns out like this: http://gyazo.com/e6f264f319cc7bab325882acae2f6097

The default holding of a tool prevents from the rest of my animation playing properly.

Even then, I can't get my animation to continue looping, instead, it only stops seconds later.

So, I'm asking; is there a way in which I can continue playing a certain animation, a pose to be precise, while holding a tool? How can I loop an animation? I've been having lots of trouble with it, and need help immediately.

Have the animation at the highest priority (Action) and to loop the box in the top right corner MUST NOT BE BLACK! It has to be tan to be looped. I hope this helps. Also when playing different animations (Reload and kick animations) DO NOT stop other animations that are currently playing. The newly played animations will override the previously played animations.
