after deployment of chart apI ver 7.0 on (Dec 7, 2011) line and combo charts stopped working.

issues...after the recent deployment on December 7, 2011 my line and
combo charts are returning an error of " 'count' is null or not an
object ". I can not find any documentation as to what this is
referencing. Following is my link to a pop up window to display my
chart and after that is the chart code.
I'm using the 1 asp page with the generic chart code in it and passin
multiple variables through the URL. Sometimes it has 7 horizontal
columns if it is displaying days of the week and sometiems it has 12
Horizontal columns if it is displaying months of the year. So I tried
to design a versital chart for multiple uses so I only have to make
chages to one block of code.
Thanks in advance for any help, or anythign that can point me in the
right direction.
