"desired salary" question on job application?

On the online job application, it asks what my desired salary would be. I research the position and it says the minimum is $13.40/hr, the mid point is $15.90, and the max is $20.80. In terms of my qualifications- my skills are on par, but my level of experience has JUST made the requested number of years. Should I be asking for anything higher than $13.40? I think somewhere between $14 and $15 and hour would be more reasonable....or would that be jeopardizing my chances?
