KDOpop100,
Welcome to the forum!
If I were dealing I would have told the small blind that it was 300 to call the big blind, so I definitely would consider the 3200 raise to a total of 3800.
There are many times, through my years of dealing, when players do not clarify their intent. Happens all the time. Player A bets 100, Player B says "raise, 300." My advice is to stop any further action and get clarification because sometimes the player's intent is actually a total bet of the spoken amount. I hope I'm clear on this. My reasoning is to prevent an unnecessary delay caused by an unclear verbal bet.
Technically, saying raise 300 should translate to 300 more than the amount required for a call but, believe me, the pause between raise and the spoken amount might not be the intended amount.
Player's must make their intentions clear.
Hope this helps.
