Drifting in leg yield

[Mule]

Hello I'm trying to learn leg yielding but I'm having a bit of a problem with coordination.
When I ask my horse to leg yield he drifts sideways instead of crossing over with his legs.
We can do TOF so I think it must be the forward motion in the leg yield that's throwing me of.
Can someone explain what I am doing wrong and how do I stop him from drifting?

If you are teaching leg yield, only ask for a couple of steps at a time, then straighten up and ask again. Start by playing with bend and forward motion, gradually asking for an increase in the lateral direction while maintaining forward movement. If you lose the forward, take it back a step.

Yes agree with above you can also just move your outside leg forward a little bit to stop the shoulder drifting that is if your leg yielding to the fence, lowering the inside hand so it's nearer the wither can also help with stopping the forehand from drifting.

Thanks that makes sense

Also if you are going back to the track try yielding away from the track instead.
