Do I have a chance with this girl I like? (she is 16 too)?

There is a girl I really like and I go to the same school as her... The only problem is that I don't really speak her at school because we are at a whole different class. I found out where she works and so I talked to her one time and that was going alright (: Now if I see her at school she smiles at me everytime and says hi or whatever but I don't really speak her. Now that I knew she works on friday in a local supermarket here I went to see her last friday (so that's for the second time). It wasn't really going that well and I know that I talked like I was very confused because I was very nervous and stuff.. xD At a certain moment she even said to me: It isn't going so well, is it? So this conversation was very very bad... but she didn't say something like: I need to go back to work or something... She was talking to me and she didn't react like.. **** off or something.. She was even trying to get the conversation going but because I'm very shy and inexperienced for a 16/17 year old It didn't go too wel.. I'm not a smooth talker. xD Now my question is.. Does she like me or not? If I will be able to get the conversation going better next time is it possible that she would like me?? I'm not sure because on one side I really screwed up.. but on the other side she didn't act like she isn't interessted.. so what do you think? (sorry for my bad language I'm dutch...:P)
