You can try <dtml-with Dict_Test> <dtml-call "Budget.remove(Budget[0])"> <!-- removes first element --> <dtml-call "Budget.insert(0,neuesBudget)"> <!-- adds new first element --> </dtml-with> Of cause, you will get an IndexError, if "Budget" is empty. You may need to provide code to handle this case. Dieter
