well, it sounds like he's in control of the URL part ... the rest, not so much. It will only work over the URL if the page was programmed to look for it. It doesn't look like this is the case. Also, given that this is in a web browser (chrome by the look of the screenshot) ... there isn't a way to "find the inputbox and add the value"... so, he's pretty much outta luck.
