getting this to compile

This should take target level and return `bool` to indicate success - if someone wants to increase his connections by 2 because they want to check an event/opportunity but did not realize that they don't have enough money this will increase the connections by one which would suck because they would loose money and still won't be able to check the event. In the ui (because it is web) it will probably be just a drop down so it will be quite natural to increase by more than one.
