If you want to create a new, simple infobox, then you might use the steps listed at my blog to create an infobox at c:xurbansimsx:Template:Infobox character or a similar location (noting that your wiki uses the new style of infobox). Customize the infobox to meet your needs, then fill in the syntax on the page.

Alternatively, since you must have copied the syntax that you are currently using from some wiki (it's not immediately clear to me which), you can copy the code of Template:Infobox on that wiki to the same page on your wiki, which will make the code on your article work fine.
