Problem with a free asp-calendar

I have writen a free ASP Calendar. That calendar works perfect, but the only thing i stumbled onto, was the coloring of special fields in the table.
When i try to change the color of holidayfields, some other fields change automaticly to that same color. can someone please check what i am doing wrong. If you want to check it out, you can download a copy of the agenda on http://www.gravenrode.nl/downloads/agenda.zip

if you surf to http://www.gravenrode.nl/agenda/diary.asp?view_date=17-Decem ber-2003 then you can see my problem in real-life. if you look close enough, then you will notice that in the top-left corner a green box. this green box has to bee blue. and that is my problem

The file in wich the changes shoud be made is diary.asp. The database is office 2000 and contains some example data. The database also is prepared to save the vacation with the date. all that has to be done is change the color of the background of the cell where vacation is checked

Read the included readmefile before you begin.

Thanks in advance for your help
