Solved how to change <none> to 0?

[wrymain]

what i mean is this:

if it doesn't find an entity from the ground, it gives <none> which i want it to be "0", anyone have a solution?

every 10 minutes:
    broadcast "&7[&eClearLag&7] &r5 Menit sebelum Sampah dibersihkan dari tanah."
    wait 4 minutes
    broadcast "&7[&eClearLag&7] &r1 Menit sebelum Sampah dibersihkan dari tanah."
    wait 50 seconds
    broadcast "&7[&eClearLag&7] &r10 Detik sebelum Sampah dibersihkan dari tanah."
    wait 10 seconds
    loop all dropped items:
        delete loop-entity
        add 1 to {_num}
    broadcast "&7[&eClearLag&7] &c%{_num}%&r Sampah Terbersihkan."

The {_num} variable would never be set if there are no dropped items lying around, because the code in your loop is never executed.
You would have to either set {_num} to 0 before running the loop or use the default value expression. (%object% otherwise 0)

You could also say:

if {_num} is not set:
    set {_num} to 0
