How to create a custom error page from scratch?

Error page needs to display error generated

[ImperialCommand]

I'm using .net2 - and trying set up a server application.
Something in the web.config file keeps breaking.
It won't display the line error code - but I think it would if I knew how to redirect it to a server generated page that contains the error code.

So I need to make a custom error page - one that will show the custom error - not just a static html page.
Am I making any sense to anyone?
Can you help?

I'm not exactly sure what you're asking (I can see several possibilities), but if you redirect it to another page, I don't think it's going to display the error unless you pass the error as a parameter. And if you can pass the error as a parameter, then you should be able to just display it on that page.

I don't know .net2, but most application server software allows you to turn on debugging to see errors- you may want to look into that.

Alternatively, [webmasterworld.com...] might be a better place to post this.

Solved.
I opened the web.config file in Microsoft Visual Web Developer 2005 (free app from ms) and it put a red underline where the code defects were made. Fixed that code mistake, uploaded the file, and the application worked.
Thanks for your response.
