How do I make the player shooting while walking?

Hello, so I am trying to make my player shoot and while he is not moving the shooting animation runs just fine, but while walking the shooting animation only plays one frame, then it goes to the walking animation. Please help

My code is something like this:

PlayerBox, on stopped > Set animation "to Idle"

PlayerBox, on moved > Set animation to "Walk"

On left button clicked > Set animation to "Shoot"

Give PlayerBox a boolean instance variable, we'll call it Shooting.

PlayerBox, on stopped & PlayerBox is not Shooting > Set animation to "Idle"

PlayerBox, on moved & PlayerBox is not Shooting > Set animation to "Walk"

On left button clicked > Set Shooting to True

PlayerBox is Shooting > Set animation to "Shoot"

Playerbox animation Shoot has finished > set Shooting to False
