iFrames - separate page and variable source html file?

Hi

I have a page where the user makes a choice from, say, 'Choice.html', which opens up say, Result.html.

In 'Result.html' there is an iFrame that will show a different source (html) page based on what they chose at 'Choice.html'.

Eg, 'Result.html' may have 'Apples.html' as the iFrame source. Or it could be 'Pears.html' as the source.

I know that it's easier enough to change the source to an iFrame when the iFrame is on the same page. But what when it's in another page?

Any clues, tips or examples woould be v much appreciated.

Regards

An example would be helpful.

You should probably use a server side language for this.
