Mohammad, I remember having an issue like this myself once, and this is how I solved it. I cannot remember WHY it works this way.
\define remove-from-begining-tiltle-bulk(myfilter, n:"0") <$list filter="[<__n__>] -0" variable=null> <$list filter=<<__myfilter__>> variable="item"> <$list filter="""[<item>split[]rest[$n$]join[]]""" variable="newTitle"> <$list filter="[<newTitle>] -[has[title]] -[[]]" variable="ignore"> <<actions1>> <<actions2>> </$list></$list></$list></$list> \end \define actions1() <$action-setfield $tiddler=$(item)$ title=$(newTitle)$ /> \end \define actions2() <$action-deletetiddler $tiddler=$(item)$ /> \end <$button> Do it <<remove-from-begining-tiltle-bulk myfilter:"[tag[xx]]" n:1>> </$button> Hope that helps.
