How to play this JJ hand.

[ahnuld]

Playing 2-4 nl on royal vegas poker with a 350 stack. Pick up black JJ in the sb. 4 limpers when the button, a regual solid player (500$), decides to make it 24 to go. I decided to flat call, since I didnt want to raise and be blown off my hand or have him call and have position on me. Sure this may have been a bad call, so please critique it and include your thoughts, im new to this limit of play.

Anyways, one of the limper calls, (Pot 88$)and the flop comes 4 [img]/images/graemlins/spade.gif[/img]q [img]/images/graemlins/spade.gif[/img]7 [img]/images/graemlins/heart.gif[/img]

I check to the raiser who bets 64$. How would you play this han donwards or what would you have done differently than me.

(My apologies if this is an obvious hand but I need to get better at hands like these as they make the difference of winning or losing)
