You have three items: SWORD, MACE, and SPEAR!
Haha! That one never gets old!
For this one, the quickest and easiest way to do it that I like is to go ahead and make three links on the page for something like, "Pick sword," "Pack mace," etc. Each of those three links should go to the next (same) page. In the script for each link you can manually make the person pick up the item with $ITEMSTATE. If the sword is your first item, you can just set $ITEMSTATE1 := 1 and they will have the item.
