if this (frm) form / form element (page_no) is not available, you will get this object expected error.

window.document.frm.page_no.value

can you give the link to test it

All the Best,

either the form is not created at the time you call this function or the name is mispelled or the form element is not available.

did u tried in other browsers like firefox,

you can easily debug using IE Developer toolbar or firebug for firefox
