// echo "".$IndexURL.$theword.$itemlink."" // non-blog page for use within a javascript call such as--- onClick="frmUpdate('<%plugin(RandomEntry_rev1,index.php)%>');
// in the alternative outputs, you can use the variable $theword to specify the url of the blog items or as in default, just specify text for link
