[Threshold]

I think you are all missing something very obvious...

pawn Код:

enum
{
    DIALOG_x,
    DIALOG_y,
    DIALOG_z,
    DIALOG_model,
    DIALOG_delete,
    DIALOG_x2,
    DIALOG_y2,
    DIALOG_z2,
    DIALOG_move
}

Why are these dialog ids in an enum for? They need to be given separate values that make them unique from each other.
Change this:

pawn Код:

enum
{
    DIALOG_x,
    DIALOG_y,
    DIALOG_z,
    DIALOG_model,
    DIALOG_delete,
    DIALOG_x2,
    DIALOG_y2,
    DIALOG_z2,
    DIALOG_move
}

to this:

pawn Код:

#define DIALOG_x 1
#define DIALOG_y 2
#define DIALOG_z 3
#define DIALOG_model 4
#define DIALOG_delete 5
#define DIALOG_x2 6
#define DIALOG_y2 7
#define DIALOG_z2 8
#define DIALOG_move 9
