		<select id="color" name="color">
			<option value="">-- Select a color --</option>
			<option value="Red" <% If color = "Red" Then Response.Write(" selected")%>>Red</option>
			<option value="Green" <% If color = "Green" Then Response.Write(" selected")%>>Green</option>
			<option value="Blue" <% If color = "Blue" Then Response.Write(" selected")%>>Blue</option>
		</select>
		<input type="submit" id="submit" value="Submit" />	
	</form>
</body>
</html>
Page 2
