What you'll probably find if you delve into it is that in the first case above, if the var wasn't set there was an error notifying you of that. In the second case above, using isset() would avoid that error message being displayed. The error you were having was because your code was displaying an error message to the browser which would automatically mean that something had been sent to the browser and it would no longer be possible to add header information. If you couldn't see the error relating to checking the var it's likely something to do with display settings for your html - eg. displaying white text on a white background. CYA, Dave
