2 colorbox opens on single click

I am using a colorbox (not in iframe) that displays node data. and another colorbox that have node form in it. Both on the same page. When I click on link that opens colorbox which displays data it opens and closes with no error. But after that I open colorbox which displays node form it gives error (Error: cboxElement missing settings object). and after this 2 same colorboxes opens. and after closing them this error comes TypeError: parent.jQuery.fn.colorbox is not a function. and JavaScript breaks.
open node form colorbox again and again gives no error.Any idea.
