Trouble With Remove Timer,Help!

[DyceDarg]

ok,i make a Timer script,but when i put the Remove Timer, i get RTE5

(i use Eclipse Evolution V1 Source)

here my code

on Scripted Spells

If GetPlayerTarget(index) > 0 Then
Call SetTimer("tmrTest4 " & index & ",3", 10000)
Call SetPlayerDEF(GetPlayerTarget(index), GetPlayerDEF(GetPlayerTarget(index)) - 30)
Call SetPlayerMP(index, GetPlayerMP(index) - 10)
Call Sendstats(GetPlayerTarget(index))
Call battlemsg(index, "Script is Fine", 12, side)

Here my Timer

Sub TMRTEST4(index, script)

Call playermsg(index, "Buff endes", 11)
Call SetPlayerDEF(GetPlayerTarget(index), GetPlayerDEF(GetPlayerTarget(index)) + 30)
Call RemoveTimer("tmrtest4 " & index & ",")

End Sub
