if u are going to raise you must first call the $2 blind. your call makes for $5 in the pot. you are raising, the amount of the pot which is now $5. so your $2 call plus $5 raise = $7

also if you are expecting a 'raise pot' to be $3 instead of $5 since thats whats in the pot with the blinds, well $3 is not even a minimum raise of the $2 blind so that not a legal betsize anyway
