i posted this question before.
now my needs are a bit different and the suggestions made before seem not to work.
any idea how i can check if fields are empty when pressing save on the web. the save button is a picture with a hotspotrectangle incluging a formular.
best would be if a message would popup displaying each field separately which is blanc (but a user definable text, not the fieldname).
e.g. "please enter the amount" if thre field amount is empty.
if the way i go for it isn't good, please also let me know.
