If I enable conditions the field is not shown anymore, before the update it was all working. I did not change anything. So it has to do with the upgrade.
I disabled the conditions now and then it is working but not as desired ofcourse.
I can enable the conditions again but then I have to do this together with a designer otherwise customers will not be able to order.
I can not keep that situation to long on the website.
Thanks for you reaction.
