Thank for your suggestions and help.The variable $title is calculated from the contents processed within the ChordPro markup, and I want to make the value held in $title available in for use outside the ChordPro markup, eg in pagelists etc. I have added the global declaration to my function. (in front of the lines shown in my example). I'm still not seeing a page variable. Do I have to tell PmWiki to 'update and save' the page? thanks again
