I have a client DB that records visits. I would like to add a field in the table that will count the actual number of visits a client has in their history. I'd like it in the table so that the field can be used effortlessly in a form, report or query.

If I use the count function in query it works as long as there is no other filters in the query. If there are other filters, then it only counts the visits from the filtered results; thus not returning the correct count of visits the client has.

This is what I actually want to accomplish. When billing the clients insurance, the user needs to know if the client is an established client or a new client since there is different billing coding for each. With the existing query, data returns with the visits that have not yet been billed by filtering the field: InsBillDate to "null". This is helpful, but the user has no way of knowing if the client is an established or a new client and the user will have to query each client to see if they have other visits on record or if they are new to the clinic.

I have a table with the following fields: VisitID; Client_ID; VisitDate; InsBillDate
I would like to add another field as VisitCount; but am unsure as to how to have this field calculate.

I am open to other ideas....

Thank everyone in advance! I have always received great advice in the past from Tek-Tips and appreciate everyone's patience with those of us that are not 'experts' in access!!
