Whats wrong here with wikify

[Mohammad]

Question:

 List all tiddlers modified on Wednesdays in 2014

<$vars pattern="^2014" day="Wed">

<$list filter="[regexp:modified<pattern>]">

<$wikify name=wday text="""<$view field=modified format=date template="ddd"/>""" >

<pre><$text text=<<wday>> /></pre>

<$list filter="[<wday>regexp[Wed]]" emptyMessage="error" variable=ignore>

<<currentTiddler>><br>

<$view field=modified format=date template="ddd 0DD, mmm YYYY"/><br>

</$list>

</$wikify>

</$list>

</$vars>

If wikify works correctly it should return Fri Wed and other modified day!

In tiddlywiki.com create a new tiddler and  Paste the above code 

see the wrong result!

What is the problem?
