I'm having a hard time getting this to work.

I have an asp.net page called CreateNewPO with a textbox called txtReqCompDate and a link to a Pop-Up calendar (NewPoCalendar.aspx).

When I click a date on the calendar I want the Pop-Up calendar to close itself and txtReqCompDate to be populated with the date the user picked.

I'm getting this error: "Microsoft JScript runtime error: 'window.opener.document.forms.0.txtReqCompDate' is null or not an object"
CreateNewPO.aspx:
