ComboBox and Textarea Box, HELP

[mlara]

Hello, how can I have a combo box:

<SELECT multiple size=5 name="shippingTypeCodes">
<OPTION value=UPR>US Postal Service</OPTION> <OPTION value=UPP>USPS Priority Mail</OPTION>
<OPTION value=UPE selected>USPS Express Mail</OPTION>
<OPTION value=UPS>UPS</OPTION>
<OPTION value=FED>Federal Express</OPTION>
</SELECT>

and a textarea box:
<TEXTAREA name=shipOther rows=4 cols=39></TEXTAREA>

work dynamically? this is what I want it to do:

If anything is selected on the combo box then the value of the textarea should "clear" if any "AND" if the textarea is selected (onmouseclick) and type a value, the values from the multiple combo box should be clear... I don't want the two values passed on to the next page. it should be one or the other.

I know this could be done in javascript, but I can't find the java anywhere in the FIND or help area of this site.


Thanks!
