Specifying event handlers in the [tt]body[/tt] tags [tt]onload[/tt] is deprecated practice. You should prefer
JavaScript: 
window[teal].[/teal][COLOR=darkgoldenrod]addEventListener[/color][teal]([/teal][green][i]'load'[/i][/green][teal],[/teal]function1[teal],[/teal][b]false[/b][teal])[/teal]
window[teal].[/teal][COLOR=darkgoldenrod]addEventListener[/color][teal]([/teal][green][i]'load'[/i][/green][teal],[/teal]function2[teal],[/teal][b]false[/b][teal])[/teal]

Note that Explorer handles [tt]addEventListener()[/tt] since version 9. If you need to support older versions too, you will also need
JavaScript: 
window[teal].[/teal][COLOR=darkgoldenrod]attachEvent[/color][teal]([/teal][green][i]'onload'[/i][/green][teal],[/teal]function1[teal])[/teal]
window[teal].[/teal][COLOR=darkgoldenrod]attachEvent[/color][teal]([/teal][green][i]'onload'[/i][/green][teal],[/teal]function2[teal])[/teal]

[ul]
[li]The [tt]javascript:[/tt] pseudo-protocol is needed only in attributes where the value is expected to be an URI.[/li]
[li]The [tt]return false[/tt] statement is needed only if you want to stop the triggered event's default behavior.[/li]
[/ul]
But if you want to continue with your old code, you can just call both functions :
HTML: 
[b]<body[/b] [maroon]onload[/maroon][teal]=[/teal][green][i]"function1();function2()"[/i][/green][b]>[/b]
