Currently I see two problems in your template, both of which are easily fixed.

Firstly, it should open with {{Msg|, not {{Msg/UE|. The double curly brackets summon a template with the name inside them, and in this case the template you want to use is Msg; as it currently stands Msg/UE is trying to summon itself. That's what's going to make it break entirely.

Secondly, you shouldn't include the type and message fields in the template's code; if you do, you should leave {{{type}}} and {{{message}}} there (i.e. the code should be |type={{{type}}} .) The triple curly brackets are where you can add things to the template when you add it to another page, and the type and message are the things that you want to be different in each use of your template, so they need to remain customisable.
