Liking a calendar to a date bind variable

Question

I have created a report using Portal application component. I also have created a calendar component
The report has a date field which is a bind variable. I want to link this bind variable to a calendar so that I can pick up date values from a calendar.
1. Is there a way I can link the bind variable to a calendar component ?
2. If not can I link the bind variable to a javascript component.

Answer 1

Thanks for your help.
My question though is the bind variable in this case the calendar date is going to be part of where clause
e.g.
select sum(invoice_amount)
from ssi_invoice
where invoice_date =: my_date
How do I link this my_date bind variable into the calendar based on what you have explained?
So basically user would have to select date from calendar before running report.
(Also need to ensure that this value selected is returned back in my_date)
