Can't get any scripts that allows my custom r15 running animation?

It's been around a week now of non stop looking for a way to get my r15 ninja run animation to work, but I can't find anything please help!

link to my animation: https://www.roblox.com/library/2410506395/NinjaRun please

So there are multiple things you may be able to do. You can either make it a tool animation, keybind animation, or I believe there may be a way to make it an animation where when you walk, run the animation can show up. I am not a scripter, but there is a link to a tool animation I have if you're interested in it. If the scripts your using are not working then I would put in your question so a more experienced scripter may be able to help you.
