Hello,

First, there were some lexical mistakes in your text. Maybe the UTF got 
mangled by copy/paste?

Second, I'm not sure if you can actually define a macro inside a macro. 
I've always kept definitions separate. So, humor me, I separated them.

Finally, whenever I find that literal text is popping up where I expect 
transcluded (wikified) text, I'm pretty sure I need the <$set> to set up 
the variables for me.

The code below is what came up with. I ditched the <<tmp>> macro since it 
didn't seem to be doing anything. The following code seems to work.

Good luck!
Mark


*\define newtitlemacro() {{$:/temp/newtitle}} <<now YY-MM-DD>>*
*\define newtitlemacro() $(mytitle)$ $(rightnow)$*
*\define newentry()*
*<$button>*
*<$action-sendmessage $message="tm-new-tiddler" title=<<newtitlemacro>> 
description=<<now "ddd, mmm DD, YYYY - 0hh:0mm $(currentTiddler)$">> 
tags="BM GL [[Hello World]]"/>*
*New Entry:*
*</$button>*
*<$edit-text tiddler="$:/temp/newtitle" tag="input" default=""/>*
*\end  *

*<$set name="rightnow" value=<<now YY-MM-DD>> >*
*<$set name="mytitle" value={{$:/temp/newtitle}} >*
*<<newentry>>*
*</$set></$set>*
