Travel Speed and Time Macro

I've tried to edit a macro and I feel I am so close to what I am trying to do. But something is off. If someone can look at the code and just see if they can spot what coding mistake, I have done I would appreciate that. !?{ft, per round} !?{Miles} !?{Pace|Normal,10|Slow,15|Fast,7.5} &{template:traits}{{name=Travel Time}}{{description=Travelling **?{Miles}** miles at (?{ft, per round}/?{Pace}) miles per hour. Takes [[floor(?{Miles}/?{ft, per round}/?{Pace}]]Hours}}

Also is there a way to change the macro, so instead, of the code outputting a number at {Pace} it outputs the text; Normal, Slow Fast.  !?{ft, per round} !?{Pace|Normal,10|Slow,15|Fast,7.5} &{template:traits}{{name=Travel Time}}{{description=Travelling **?{ft, per round}** ft., per round; At a **?{Pace}** Pace. You would be moving [[(?{ft, per round}/?{Pace})]] Miles Per Hour}}
