Need new script for using weapon when out of spears!

[Lillerik]

Hiho ive got an old script that puts a weapon on my hand when im out of spears in my hand:

$numericalexp:{$countitems:CD 0C$}-{$hex-equiped-item:06$}$
#number>=#
0
1000
1000
0
exiva > 78 FF FF 40 00 00 CD 0C 00 FF FF 06 00 00 01
$countitems:CD 0C$
#number=#
1000
0
1000
0
exiva #E1 0C 06
The script works but it gives a constant "sorry not possible" message while Im using it
so I need a better one that is more stealty to avoid detection.
