APEX 32 Calendars

Question

Hello Gurus.
I have a page where it contains a calendar region and an interactive report region . And both region share a column called Account#.
The requirement is, if user clicks on a date on the calendar where Account# is hyper linked. The interactive report should only fetch all rows pertaining to that account only.
How can I achieve above?
In detail:
1) How can I create Hyperlinks on dates where account# is visible?
2) Then, How to link those account# link with interactive report link?
3) How to make Interactive report region automatically synch up with clicks on calendar dates(where account# with hyperlink is shown).
I have looked at the sample application page 4, but it is different than what I need to achieve.
Thanks,
R

Thanks Kartik,
With your help, I am getting there.
I am now able to link calendar dates, but now when I click linked dates on calendar, it opens up a new window and throws the error with "HTTP 400 BAD request " error.
I wanted to show this through demo on apex.oracle.com but, they have now APEX4.0 where as my app is still in APEX 32.
Below is what exactly I did.
Step 1.
Create a classic sql report with following
select      "DEMO_ORDERS"."ORDER_ID" as "ORDER_ID",
      "DEMO_ORDERS"."CUSTOMER_ID" as "CUSTOMER_ID",
      "DEMO_ORDERS"."ORDER_TOTAL" as "ORDER_TOTAL",
      "DEMO_ORDERS"."ORDER_TIMESTAMP" as "ORDER_TIMESTAMP"
from      "DEMO_ORDERS" "DEMO_ORDERS"
WHERE ORDER_ID = :P7_X
2. Report is conditional - SQL Query returns at least one row:
SELECT 1
  FROM demo_orders
WHERE order_id = :P7_X
3. Calendar query is:
select O.ORDER_ID, order_total ord, order_timestamp
from demo_orders o
4. Calendar display type is CUSTOM and column format is:
<span style="color:darkred;font-weight:
bold;font-size:14px">#ORD#</span>
<span style="color:darkgreen;
font-weight:bold">USD</span>
  </br>
<a href="f?p=&APP_ID.:7:&
SESSION.::NO::P7_X:#ORDER_ID#"
style="color:darkblue;
font-weight:bold">#ORD#</a>I have exactly followed steps outlined in the link given, but still when I click on calendar dates, instead of toggling the report region on same date, it opens up a new window with above HTTP error.
I am not sure what am I missing :(
Thanks,
R
