Hi,
Thank you very much for your answer. It works perfectly, except I am not able to get the orange colour to work. No matter what colour code I put in here for the code representing "one month in advance", it just turns out light green. I can however live with that, unless you see an easy explanation for it. When I try to change colours for the other dates, it works perfectly, so the only problem is this field.
Kind regards,
Renate
