自動精煉武器問題

automacro boob {
inventory "笨拙短劍 [4]" == 0
run-once 1
exclusive 1
call {
$a = 笨拙短劍 [4]
$num = 1
$num = $num + 1
$num = $num + 2
$num = $num + 3
$num = $num + 4
$num = $num + 5
$num = $num + 6
$num = $num + 7
$num = $num + 8
$num = $num + 9
while (@storamount($a) == 0) as loop
if (@storamount($a) > 0) goto aa
if (@storamount($a) = 0) goto bb

:aa
do storage get $a 20
do storage get 強化武器金屬-級數一 20
pause 1
do ss 477 10
do refine +$num $a
release boob

:bb
do storage get +$num $a 20
do storage get 強化武器金屬-級數一 20
pause 1
do ss 477 10
do refine +$num $a
release boob
}
}

這樣迴圈是不是寫錯了
