Using an ICON to link to a web page

I have a icon and I have set up a script to make it clickable. When I click on the icon, it isn't loading anything. This is the code I have. Is this not possible with icons?

Subprog CL_ZPICDOWNLOAD(VALEUR)
Variable Char VALEUR()

Callui RETOUR="" With "UIAction="+chr$(1)+"OpenFile", "UILocalDir="+chr$(1)+"HTTPS", "UILocalFile="+chr$(1)+"GOOGLE.COM"

End
