Dropdown box with Variable - Settings

Hi Gurus

I work with the Web Application Designer 7.0 In the Template i have a dropdown box with a variable (SV) for 0CALYEAR.

In the template the dropdown box show a list like this:

show all values

2001

2002

2003

2004

I only want to show the years. what can i do to exclude the "show all values" and "#" ??

I found nothing about this in the forum.

Many Thanks in advance
