I wonder if you can help please?

I have a normal web page that contains a link.

When the link is pressed a javascript popup window occurs asking the user for a choice.

The popup window then closes and I want also for the original page to be refreshed.

So how do I do the refreshing is my question.

I realise the reload command is relevant, but am unsure on how to tell the pop up window to refresh the original page.

Thanks if you can help,
