Forum:Some help needed with templates

I was wanting to make a template display " " only if the field "Name" has something when the template is used. How is that possible? -- Sam Wang (talk) 11:49, July 21, 2012 (UTC)

 * Be careful. The names of parameters are captial sensitive, so  is a different parameter than  . I usually use only lower case letters to avoid this problem.

 * I have another question similar: is it possible to display  if the page "Message Wall:Sam Wang" exists or else display  ? I want to use it for my signature, thanks -- Sam Wang (talk) 21:16, July 21, 2012 (UTC)


 * Perhaps ifexist is what you're looking for? -- 21:50, July 21, 2012 (UTC)


 * doesn't seem effective inside of the signature field. Last time I tried to use it but it didn't work.
