"Break to"problem

my question is
first, I set the label on the "item".
second, if when robot10 loading the "item" whose value is 1 of label"G",during the loading time 20 secs, the "item" whose value is 2 of label"G" get into Queue5, then the robot10 will stop loading the "item" whose value is 1 of label"G" and then directly loading the "item" whose value is 2 of label"G" ~
now, I wrote my own TS in "Request transport From" ,
and in TE's " break to "Requirement , I set the TS will break to new TS
by specific label "G" == 2 . But it seems can't work @@

if anyone can give
me some idea , I will appreciated you so much~
