I have a form with a number of combo boxes, the selection of the first decides the values in the second. The remaining boxes all have static rowsources.All the Values are chosen and then added together. The problem that I am having is resetting all the combo boxes to '0' in order to perform the task again cleanly. I have tried using

cmbcase = Empty
or
cmbcase = null

they all return to the ‘empty’ state except the combo box whose content is affected by the previous one which will not change back.
Am I missing something obvious

Help!!!

Hmmm. I tried this and it worked for me. I did use the syntax of Me![ComboBoxName] = Null but I do not think that is the problem. I do not know what is happening in your case....
