Admin Forum:Redesigning the Delete template

We have decided to modify our template and adopt wikiHow's deletion policy, which uses three-letter codes instead of manually typing a reason (i.e.  ). You can read about it here. Currently, our wiki uses. Being an active editor at wikiHow, I've gotten community manager's permission to emulate their template.

However, I am not good at advanced syntax, especially when it comes to templates. How can I write the code so that the original message, "This article has been nominated for deletion. This reason for this is:" stays, but the three-letter code is the parameter that changes? Basically, for us, one exmaple would be, which would make "This article has been nominated for deletion. The reason for this is: Personal player pages are not allowed."

Thanks! :)
