Creating an Open, Save, and Cancel Dialog box

[Jude]

Please help,

Im a newbie and all i can find is complex code for the wrong thing i am looking for.

All i need is a simple dialog box, i have a website whereby when the user clicks the link i want a dialog box to pop up asking the user whether they want to open, save or cancel the operation.

Although this may seem simple i have no idea where to start ive hit a mental block, as this isn't my usual programming code.

Please help its much appreciated

Many thanks
