Ruling question, string bet or no?

floorman said he can keep going back to his stack as much as he wants, then another floor said he needs to announce his raise amount verbally.

I am very slow this morning; only finished about 1 cup of coffee. Help me out here - If you announce "raise," you must raise at least the ammount of the bet. If you announce "raise $400," you can go back and forth to your stack until you finish puting in $400 more. So if the bet is $80, you just say "raise," push a stack of $150 PAST YOUR CARDS, the dealer will tell you you can only put in $10 more. No?
