Why is my Teleportation command not working as supposed to?

I have checked, and rechecked what could I have done wrong, but I do not see any errors, I have added a few prints to see which ones would print, and Chk1 was the only one that would print, it did not print Chk2 nor Chk3 aswell, also if you typed '_tp me' the script would break for some reason, I do not know how to fix this command anymore, I have already conducted numerous tests to get it to work, here is the script;

if msg:lower():sub(1,3+#Prefix) == Prefix.."tp " then
local chk1 = msg:lower():sub(4+#Prefix):find(" ")
local plrz = GetPlr(plr,msg:lower():sub(4+#Prefix,chk1-1-#Prefix))
local plrz2 = GetPlr(plr,msg:lower():sub(chk1+1+#Prefix))
print("Chk1") --It will only print this
if chk1 then chk1 = chk1  + 3+#Prefix end --I've tried this to keep from getting the Error, but it still comes up after typing '_tp me', and breaking the script for some reason
for i,v in pairs(plrz) do --Sadly when it gets here, it appears to stop
print("Chk2") --It will not print this
coroutine.wrap(function()
for i2,v2 in pairs(plrz2) do
print("Chk3") --Nor this
if v and v2 and v.Character and v2.Character then
v.Character:MoveTo(v2.Character.Torso.CFrame:GetModelCFrame().p+Vector3.new(0,1,0))
end
end
end)()
end
end
