Excel VBA script to automically go a a webpage and click on a button

Hi,

I need help to find codes to automatically go to a site and click on a button
For example:

Click on: Demo>Open Page>In Same Window (this button only on the horizontal blue bar)

Cheers
Daniel

By the way, here is the site

It is totally dependent of the code with which the websitepage is created.

hmm.. how would you code if I would like to automatically click on the button below

"var pmSame00 = new TPopMenu('in same window','','a','index.html','Open page in same window');"


The whole menu coding is as per below

var mm0 = new TMainMenu('mm0','horizontal');
	var pmDemo00 = new TPopMenu('Demo','5','','','doiMenu v.1.5 demo');
	var pmIcon00 = new TPopMenu('with Icon','','','','with icon');
	var pmFav00 = new TPopMenu('Favorites','../img/favorites.gif','','','favorites');
	var pmHist00 = new TPopMenu('History','../img/history.gif','','','History');
	var pmHome00 = new TPopMenu('Home','../img/home.gif','','','Home');
	var pmSep00 = new TPopMenu('-','','','','');
	var pmRef00 = new TPopMenu('Refresh','../img/refresh.gif','','','Refresh');
	var pmStop00 = new TPopMenu('Stop','../img/stop.gif','','','Stop');
	var pmOpen00 = new TPopMenu('Open page','','','','Open page demo');
	var pmSame00 = new TPopMenu('in same window','','a','index.html','Open page in same window');
	var pmDiv00 = new TPopMenu('in new window','','f',"newWindow('index.html')",'Open page in new window');
	var pmL00 = new TPopMenu('Long popup menu','','','','Popup menu demo');
	var pmAlert00 = new TPopMenu('Alert','','f',"alert('You have clicked me!')",'Alert');
	var pmHelp00 = new TPopMenu('Help','','','','Help');
	var pmAbout00 = new TPopMenu('About','','f',"alert('doiMenu v.1.5\\nThis is freeware\\n© 2003 Donna Iwan Setiawan')",'About this program');
	mm0.Add(pmDemo00);
	pmDemo00.Add(pmIcon00);
	pmIcon00.Add(pmFav00);
	pmIcon00.Add(pmHist00);
	pmIcon00.Add(pmHome00);
	pmIcon00.Add(pmSep00);
	pmIcon00.Add(pmRef00);
	pmIcon00.Add(pmStop00);
	pmDemo00.Add(pmSep00);
	pmDemo00.Add(pmOpen00);
	pmOpen00.Add(pmSame00);
	pmOpen00.Add(pmDiv00);
	pmDemo00.Add(pmL00);
	mm0.Add(pmAlert00);
	mm0.Add(pmHelp00);
	pmHelp00.Add(pmAbout00);
