You still have not shown enough code to enable us to see what's happening.
All I can say is that you should determine which object it is complaining
about: tdBWOM or sb1. Insert some code to verify that both of these
variables are set to the appropriate objects.
You should do this before posting more code. :-)

Here is the line of code:--------
tdBWOM.InnerHtml = sb1.ToString();
In an attempt to isolate what is happening, I changed the html file
to use a html table instead of an asp:Table. I get the same result.
I cannot get this to fail on my test system, only on the production
server. When the page first displays, the text I put in the cell
displays perfectly. There is no error. Only when I navigate to
another page on the site and then navigate back to this page do I get
the error. If you want to see the aspx page after it is generated,
go to www.mafe.org. It is the home page for the site (default.aspx)
that I am having the problem with. I currently have the line of code
above commented out in the code behind file. --

It's easy to debug if you step through it and add a breakpoint on
that line...

I have a real stumper. I added a server side table to a home page
that has two other server side tables on it that have been working
great. In Visual
Studio everything works great. When I put the page on the
production server,
the first time in the page works great. If I navigate to any other
page on
the site and then try to return to the home page the control I added
throws
the following:
Server Error in '/' Application.

If I comment out the line of code where I store a row in the new
table, all
works just fine. Anyone have any ideas?
