There were extra spaces on your script. It existed in at least 4 lines on your script. Find the lines below and remove highlighted:


if (KM1.checked && INCHES2.checked) {document.write(INPUT.value*39_370.0787)}
.
.
.
if (KM1.checked && YARD2.checked) {document.write(INPUT.value*1_093.6133)}
.
.
.
if (MILES1.checked && CM2.checked) {document.write(INPUT.value*160_934.4)}
.
.
.
if (MILES1.checked && INCHES2.checked) {document.write(INPUT.value*63_360)}


..the areas highlighted above which are underscores are actually spaces on your end. I did that in order to highlight the issue properly.

Hope that helps.

Rangana: Those extra spaces are often put in by this forum's software, for no reason I've yet to find.

I don't think that has anything to do with his problem.

NoCode: You will need to pretty much start over.

If you use document.write *AFTER* a page is fully loaded, it WIPES OUT the ENTIRE page!!! Even including the javascript code that did the document.write.

This means that you can NEVER use document.write to respond to any kind of user input or any kind of user-initiated event.

But there are many other things wrong with your code.

YOu keep using the IDs of the radio buttons as a means of reaching them. That *ONLY* works in MSIE browsers (and maybe not even then in MSIE 9). In all other browser you would need to use document.getElementById(...) or some other construction.

You'd be well off just tossing this effort and starting over.
