I have been trying to get javascript to work for this but no luck. What I am needing is: I have a drop down box for a person to select COUNTRY either US or Canadian. If it is US then I need a zip code box to display and validate zip for US. If they select Canada I need the same box to validate for Canadian zip code. Any ideas or help with this would be very much appreciated. Can this be done in .asp? If not I can send the javascript code that I can't get to work if that would help.
<select name="COUNTRY" id="COUNTRY">
<option value="United States">United States</option>
<option value="Canada">Canada</option>
</select>
<input name="ZIP" type="text" id="ZIP" size="7" maxlength="10" />
