acessing variable from a page

How do I access a variable from a page.

I keep coming across this:

myurl.cfm?variablename=value

but I just need GET the variable

So I need the corrent syntax for:

<cfoutput>
myurl.cfm?#myvariable#
</cfouput>

where #myvariable# is a variable from that page.

thanks

If you run a CF page with a URL like this:

index.cfm?username=joe

then you can get at that variable on the page like this:

<cfoutput>
#url.username#
</cfoutput>

If this isn't clear to you I strongly urge you to read the documentation or pick up a good CF book, because this is about as basic as anything in CF development can be.
