Parkour with checkpoints and command blocks.

Someone pls can make me work this on 1.20.4?
I have a region and checpoints.
The first command block is a repeating command block
/execute if entity @a[x=10,y=96,z=8,dx=10,dy=0,dz=11] run say You fell out!
The second one is a chain command block.. Its
not working and i dont know why not teleport it to the player to x16 y96 z8.
/execute if entity @a[x=10,y=96,z=8,dx=10,dy=0,dz=11] run tp @a[x=10,y=96,z=8,dx=10,dy=0,dz=11] 16 96 8
