I have a question for you guys... Here is some code:

<html>
<script language=javascript>
document.write("<Form>");
for(x=0;x<3;x++)
{
document.write("<input type='button' Name='test'+x onclick='OpenLink(x)' value='value'>\n");
}
document.write("</Form>");
function OpenLink(x)
{
alert(x)
}
</script>
</html>

It generates three buttons and runs the OpenLink function when you click on one. The problem is that all of the buttons return what x is currently at (3) when the button is clicked. I wan't them to return the number of the button that was clicked. I hope that wasn't to confusing... :) Let me know if you don't know what I mean... Thanks, Adam

it is obvious why it is doing what you say.

you are counting to three while generating three buttons.

then after the count is three you are using that same variable for a result. of course it will always be three.

now for as to what you want . . . you need to use the value of x rather than the variable x where you have openLink(x) in your document.write.

document.write("<input type='button' Name='test'+x onclick='OpenLink(x)' value='value'>\n");

This line needs to be changed to

document.write("<input type='button' name='test" + x + "' onclick='OpenLink(" + x + ")' value='value'>\n");
