Business Process on Quotes

Hello everybody,

I created a business process for quotes:

If the quote total amount is more than 5000$ the next step is to approve the quote by our management before sending.

The problem is, that the business process does not change at runtime.

Example:
I create a new quote. During "FormLoad" the total amount is 0$. Because of this the business process skips the approval step because the condition is not true. After that I add products to the quote. Unfortunately the business process still does not change. Only after clicking on "next process step" and then clicking on "previous process step" the approval step is visible.

Does anybody have an idea?

Br,
