Forum:Parser Question

Hello everyone! I don't have much knowledge about parser functions and haven't been using them long, so I'm hoping I can get some advice. Specifically, I'd like to know if there's a way for the classic   template function to be made to not require the parameter  x=  in the destination for the function to still produce a blank. As it stands, not including  x=  would still produce y. If anyone can help, I would certainly appreciate it! -Revitalizer (talk) 22:33, August 23, 2012 (UTC)

"If" checks if the test field is empty. But the parameter will render as just that when called in a template. That's why you need to define "nothing" as a fallback default for x.--PedroM (talk) 23:14, August 23, 2012 (UTC)
