Teleportation with blocks

[JustADev]

Question: How do I make it so when a player right clicks the sword and teleports, that if there is a block in front of them, it will teleport them 1 block away from the block?

Code:

on rightclick with diamond sword:
    name of player's tool is "&eEnderman Sword":
        set {_Waited} to difference between {Teleport::%player%} and now
        if {_Waited} is less than 20 seconds:
            stop
        else:
            set {AbilityInUse} to "True"
            send "&cAbility &8&l» &7You have activated your &aTeleport &7ability" to player
            set {Teleport::%player%} to now
            set {_Block} to block 4 in front of player
            play "ENDERMAN_TELEPORT" to player at volume 1
            teleport player above {_Block}

Which portion of the code doesn't work and are there any errors? You've posted here enough to know the drill by now huh? ;3

Ok, the code I created is 100% perfect, Its just finding a way so that if there is a block in front of the player, it won't teleport them through it

Example:
o = you
- = block on ground
| = 2 high block stack

o--|-
I dont want them to teleport through it.
I tried looping the blocks above {_Block} in a radius
But It didnt work, no errors though

on rightclick with diamond sword:
    name of player's tool is "&eEnderman Sword":
        set {_Waited} to difference between {Teleport::%player%} and now
        if {_Waited} is less than 20 seconds:
            stop
        else:
            set {AbilityInUse} to "True"
            send "&cAbility &8&l» &7You have activated your &aTeleport &7ability" to player
            set {Teleport::%player%} to now
            set {_Block} to block 4 in front of player
            loop all blocks in radius 4 of {_Block}:
                if loop-block is block 1 above {_Block}:
                    cancel event
                else:
                    play "ENDERMAN_TELEPORT" to player at volume 1
                    teleport player above {_Block}

If I under you correctly could you not just check if the loop block in a radius or vector is not air and if not cancel it?
