Object reference not set to an instance of an object??

Reapes

Hi Group,

I wonder if any smart people out there can help me ...

I keep gettng Object reference not set to an instance of an object whenever
I run my aspx page.

I cannot understand why I keep getting this as a while ago this page worked
fine with as far as I can tell no modifications. I have underlined the line
where it throws the exception. I am using DreamweaverMX's Datasets if that
makes any difference :)

I have included the code down to the error line if that helps...

Thanks

Quickly looking at it, my guess is that Request.Cookies("shopGuid") doesn't
exist, so when you try to access the "Guid" value of something that doesn't
exist, it's crashing.

You should check to make sure Request.Cookies("shopGuid") isn't nothing
before tryin to do anything to it..
