i error opengallery not defined. wrong doing?

your javascript syntax invalid, should getting syntax error in console. should be:

function opengallery(url) {       $.colorbox({width:"80%", height:"80%", iframe:true, href:"/pagetoopen.html"}); } 

var used declare local variables in function body. function arguments automatically declared local, var keyword not used there.
