Hi, I have the following problem:

I am a sports better. and i use www.betfair.com to do online betting. when there is an event, the odds are refreshed every 20 seconds or if i click a little refresh button on the page.
i have spent hours and hours reading through loads of forums to find a way to locate that element in the webbrowser.document.elements section. but i cant find a way of clicking it.. i have looked at the source code and theres an image, with an onclick="RefreshMarket();" so ive tried to use :

web.navigate("javascript:RefreshMarket();")

it wont work, will give me an error.

If someone has time, or has a similar question and has any information please help me.
Thanks a lot
Phillipp
