Custom character is not moving

so, i have made a simple custom character and there is an issue with it movements.
it keeps stuck and isn’t moving a muscle. Does anyone know a way to solve this problem?

Here is the character model:

Thank you for reading, sorry for my poor grammar skill.

thanks for the character model this is gonna go great in my fnaf game

(all jokes aside, this looks like an issue with the anchoring of the model.)

Here are some tips:

If this is a playable chracter make sure its name is StarterCharacter

Make sure all parts are unanchored. And turn cancollide off

Make sure the names are correct if your rig is r15 (example: RightUpperLeg, LeftLowerLeg. And the joints should be Right Shoulder, so dont forget the space between each word for the joints.)

Make sure you have the correct welds.

Make sure the models primary part is the HumanoidRootPart or it will not move.

Hope this helps you!
