Forum:Template variable default problem

Ok i have this template i put on Wikia:Sandbox

Now my issue is that im using  supposedly if nothing is put on elemento it should appear N/A.

So if i type this: This happends:

As you can see the N/A did not appear...

In order for me to work i need to completely remove the " " line and i get my result as i wanted like this:

Any one know why it's not working like it use to? --
 * Try using  instead. That's what I do with I encounter this sort of problem. I'm not sure why   doesn't work, however. --Michaeldsuarez (Talk) (Deeds) 13:29, 30 April 2009 (UTC)
 * Already did that, but thats not my question. I wish to know why is not working as is use to --


 * I think the problem is, you're not leaving the field blank (which would make the default variable appear), you're adding a linebreak as the value. 14:30, 30 April 2009 (UTC)
 * But that in the past was not an issue and it was tread as blank so (again)... why is not working as it use to? --


 * That's because you need to use the parser function, because ParserFunctions trim the whitespace inside the parameters. Template variables won't ignore whitespace or linebreaks. This is handled by MediaWiki in this way since always. --Ciencia Al Poder (talk) -WikiDex 17:46, 30 April 2009 (UTC)
 * Yea, i can confirm it always was like that.
 * For the N/A to appear when not using the parser function, you need to remove the |elemento= part from the template call. — TulipVorlax 01:22, 1 May 2009 (UTC)
 * mmm well i still dont remember it did that when i started to create templates in 2006 before i switch to old qif template trick and then to parsers any way thanks for the feedback --
