Help with drop down macro

What am I doing wrong here? I want to be able to select the weapon from the drop down table and roll the table for the rest of the properties. Here is my code: &{template:npcaction} {{rname= Choose Weapon}} [[?{Which Weapon|Bastard Sword|Battleaxe|Broadsword|Club|Cutlass|Dagger|Elven Longsword|Flail|Glaive|Greataxe Greatclub|Greatsword|Handaxe|Halberd|Hand Wraps|Light Hammer|Longsword|Lucerne Hammer|Mace|Maul|Pike|Quarterstaff|Rapier|Scimitar|Short Sword|Sickle|Spear|Straight Sword|Trident|Warhammer|War Pick}W?]] [[1t[MagicMeleeWeapons]]] }}

That will result in something like this in chat: &{template:npcaction} {{rname= Choose Weapon}} [[Short SwordW?]] [[1t[MagicMeleeWeapons]]] }} Which isn't valid.  I don't know how to construct what you're after, but I know that a problem on the road to the solution.  You will likely run into some order of operation issues with the expansion of Roll Queries and inline rolls and such.

Ok Thanks.
