Need Help in HyperLink with query string

Here is my problem:

I am passing a Customer ID using query string, however I also want to pass in a mode.  For example if the user clicks edit, I am using the hyperlink to re-direct them to the update Customer page.  In the hyperlink control I have a query string that is passing Customer ID and that works great, I also want to pass in MODE="E" (mode equals edit).

I am using the same Customer Edit page to edit current customer information and I am accessing it from an Add New Customer button.   I want to be able to pass in mode so I know whether they are editing or adding a new record.  I will then using this in code to determine what to do.

Here is what I have tried:

<asp:HyperLink ID="customer" runat="server" NavigateUrl='<%# "CustomerEdit.aspx?ID=" + Eval("CustomerID") &MODE="E" %>' Text="Modify" />

I keep getting an error that MODE does not exist in the current content...

Any suggestions???

First I will say I googled (Binged to make Bill happy) for this but could not find anything, perhaps I am not stating what I need correctly;

I have a website that a customer creates orders (for a printing company) and after the order, I would like to email the customer a link to view the status of their order;

I need to send the CustomerID in the link so on the returning page if a CustomerID is detected in the querystring, I "auto login" the client and open the "Dashboard" for the order page for that customer.

Can anyone point me in the right direction as to how to send the link and how to parse the querystring to get the values from the link;

Thank you if you can point me in the right direction.
