My name is Zach Dennison, and I joined Wikipedia on May 12, 2005. I am always using Wikipedia as a resource, yet I am fairly inactive when it comes to editing and creating articles. My biggest interest is in computers. I can write batch, HTML, and PHP files, and I can write in wiki markup. Most of my article contributions are to correct typos or add a small amount of content to an article.
Do you have a list of possible choices for a template parameter? Use the #switchparser function to define the choices. Then simply enter the choice's numeric value into the template for the applicable parameter, e.g., 1="Sunday" 2="Monday" 3="Tuesday" ... Default choices also can be listed. For simplicity with lists, use a switch statement instead of a "nested if-then-else" conditional statement to control flow.
