Some help for a noob with buttons

There has to be a way to do what I want to do but I'm fugged iif I know how. Here's the problem...

A page has three frames - top, left and disp. Top and left contain a number of buttons that display another page in disp. All the buttons need to behave as one set of radio buttons; when a button is clicked any other button returns to the non-clicked state. The really awkward bit is there's an image in top that changes depending on the currently clicked button and that image is behind the buttons.

Here it is in pseudocode of sorts.

On click button[n]
Button[LastClicked].Image := Button[LastClicked].UnClickedImage;
Button[n].Image := Button[n].ClickedImage;
Top.Image := Button[n].TopImage;
end;I hope that makes sense. :)

If some kind soul has any idea of how to do that I'd be very grateful.

Thanks.

Simon.

So the buttons show their state? That is, do they change from one color or text or image to another when they are clicked on and thus active?

It would help if you'd show your HTML, even without the JS code.

type BUTTON
string: ImageFileName;
string: ImageFileName;
string: PageFileName;
function ButtonClickHandler(BUTTON: Sender) integer;
end;

function ButtonClickHandler(BUTTON: sender) integer;
integer: i;
begin

end;
array [1..10] of BUTTON: buttons;

type BUTTON
string: ImageFileName;
string: ImageFileName;
string: PageFileName;
function ButtonClickHandler(BUTTON: Sender) integer;
end;

array [1..10] of BUTTON: buttons;

function ButtonClickHandler(BUTTON: sender) integer;
integer: i;
begin
for i := 1 to 10 do
button[i].image :=

end;

Argh! How do I delete the posts. :S

Could you answer my question??

I think what you want is trivial, but I would *REALLY* like to see the HTML of the page.

Ah... problem is... I haven't written the html yet. 'Cos I know the html isn't going to need Werner Von Braun so I decied to del with the sticky bit first. 90% of the coding takes 10% of the time. ;)

I haven't got all the images yet but I'll try and throw something together this evening and post a link to it on here.
