or just "until Storage Empty", "until Storage half Full" and "until Storage Storage Full"
that way to have your to only have 1 item in box use the code under
forever
repeat until storage Empt
goto 1:1 (wait until box is empty)
repeat end
do your stuff
forever End
But the correct way is to have multiple drop down menus: ()=one drop down menu
Repeat (until Storage) (=>,<=,=)(0,50,100% Full)
