How do i find xpath for a button on web page

Hi,
I am having trouble finding the xpath so i can click the NextButton button on the web page.
The IDE does not click this button. If i can find the xpath i can write it in my C# code and then run it in Nunit.
The code snippet is:


a id="uxNextButton" class="signup-submit-button" href="javascript:__doPostBack('ctl00$BodyContentPlaceHolder$uxNextButton','')">Next step'

I right click on the button and select View Xpath. The Xpath it gives is: id('uxNextButton')

In my C# i write selenium.Click("xpath=id('uxNextButton')");
It does not work.
Please help, what is the xpath for this NextButton?

if i m not wrong u can use firebug,,if u are aware about it then well n good , otherwise for ur information this is a mozilla extension... u can install it through seleniumhq.org site...

after installing it u can right click on the web element then find the option

INSPECT ELEMENT WITH FIREBUG

then it ll give u the selected code there u can right click n copy the xpath
