just use the following line to remove all the previous options in the select tag before all for loop those binds new data to 2nd combo box:

document.ikki.brand.options.length=0;

I have A question... How can I select the content of brand here...Example : when I selected in the Menu like for Example CARS, the Options will display in "Brand", but when I started to select the 2nd to the last option, the only value that appears is the first value like "Toyota"...

in your HTML you have line like following:

Expand|Select|Wrap|Line Numbers

<select name="brand" onchange="ikel()" ></select>

here, "onchange" Event creates the problem for you. when ever you click an item in "sel" select tag the values of "brand" select change because of "ikel()" function in "sel"'s "onclick" event.

similarly, whenever you select an option from "brand" item, it calls the "ikel()" function that used in "onchange" Event of "brand".

So, remove the 'onchange="ikel()"' from the "brand" select tag.

Hope you understand. :)
