Nametags (Above Head)

[iParis]

Hi,

I'm trying to have nametags and I'm struggling a little bit. I'll show my code and what I need help with but at the moment I have it semi working as an On Join event however sometimes it doesn't show up or it just doesn't refresh at all. Then I tried to make it like refresh every 2 seconds however that didn't seem to go well.

on join:
    loop all players:
        make loop-player see player's prefix as "&7"
        make player see loop-player's prefix as "&7"
        if player has permission "{@DefaultGroupPerm}":
            wait 1 tick
            make loop-player see player's prefix as "&7{@DefaultGroupTag}"
        if player has permission "{@DonorGroup1Perm}":
            wait 2 tick
            make loop-player see player's prefix as "&a{@DonorGroup1Tag}"
        if player has permission "{@DonorGroup2Perm}":
            wait 3 tick
            make loop-player see player's prefix as "&a{@DonorGroup2Tag}"
        if player has permission "{@DonorGroup3Perm}":
            wait 4 tick
            make loop-player see player's prefix as "&b{@DonorGroup3Tag}"
        if player has permission "{@DonorGroup4Perm}":
            wait 5 tick
            make loop-player see player's prefix as "&b{@DonorGroup4Tag}"
        if player has permission "{@YouTuberGroupPerm}":
            wait 6 tick
            make loop-player see player's prefix as "{@YouTuberGroupTag}"
        if player has permission "{@OwnerGroupPerm}":
            wait 7 tick
            make loop-player see player's prefix as "{@OwnerGroupTag}"

Am I doing anything wrong? or what
