Logic jumps : multiple choice questions

Hi, I hope I can get some help here. 

I’m struggling with logic connections. In one of my forms I have a multiple choice question. The problem starts when the respondent choose more than one option, then only one connector is taken in consideration. The result is that the respondent cannot answer the rest of the form, as the final message come out. 

Thanks a lot for your help!
