Help with "Map.UseOn" command

[Bugre]

Hello, I am trying to use potions on another character, but the macro command is not working.

Here it is:

Map.UseOn(268, 99, 32153, 31660, 8, 0)

(Map.UseOn(ID, OnID, X, Y, Z, Range))

Am I doind something wrong?

Using Macro Debug it returns this:

Start-Of-Macro

Map.UseOn(268, 99, 32153, 31660, 8, 0) returned 0
End-Of-Macro

There is a character on the position...if I try the Map.HasID command:

Start-Of-Macro

Map.HasID(99, 32153, 31660, 8) returned 1
End-Of-Macro

Please help me.
