how to add check all in my script
 

hi,

i programed a script have check box behind every item
i need to add button to sellect all and another button to deselect all
i added this but its not work

And you've defined the function checkall in the page? You can't just add those lines. You need to use javascript to select all or deselect all, so you need some code to do this, not just a couple of lines like you have.

i know that
i used this function from /clientscript/vbulletin_global.js?v=382
