ASP Classic duplicated variables

[robsuttonjr]

At the top of an classic asp page I set the variable:
CustomerID = Request.QueryString("CustomerID")

At the bottom is a back button. When they click it more than once the CustomerID duplicates appending the same value with commas.

<input type="button" value="Next Week ----->" onclick="window.location.href = 'InvoiceItem_list1Week.asp?txtDate=plusweek&CustomerName=CustomerName&CustomerID=<%=CustomerID%>'">


Any ideas on how to prevent appending duplicates?

Regards,

Rob

I think the problem would be in the code that executes in InvoiceItem_list1Week.asp ?? For starters, you should show that code.

I may have figured it out. But I need some understanding of how to handle a value passed with spaces & '&':

This causes duplicates:
<input type="button" value="Next Week ----->" onclick="window.location.href = 'InvoiceItem_list1Week.asp?txtDate=plusweek&CustomerName=CustomerName&CustomerID=<%=CustomerID%>'">

This does NOT:
<input type="button" value="Next Week ----->" onclick="window.location.href = 'InvoiceItem_list1Week.asp?txtDate=plusweek&CustomerID=<%=CustomerID%>&CustomerName=CustomerName'">

Key her is putting the value which has spaces and other special characters in it last.

URLEncode()

I agree with Chris about Server.URLEncode, but I still don't get how this causes "duplicates appending the same value with commas". Has to be something in the code in InvoiceItem_list1Week.asp, and I'm not sure the URLEncode will fix that?
