As an update, is there also a way to make the autocomplete field prepopulate with some data? i.e. what I’m really trying to do is to get the 2nd autocomplete field to prepopulate with the PostCode lookup (with the highest ID number in the lookup list) that matches the selection made from the 1st autocomplete lookup, this way my users could enter an account name which would set the actual lookup value of the account field, this in turn gives me the ID number of the account field lookup column in my 2nd list, now if there are 1, 2, 3, 5, 10 etc. entries for that account in the account contacts list, id like to pull back the post code for the last item added into the contacts list where the account matches the one I selected.
Thanks
