    Populate a field based on combobox selection

    I would like to populate a (another) table field based on user combo box selections.

    I would like a combo box with selections A, B, C, D, E, etc.



    If combo box A is selected, it would populate with the numeral 1; if B were selected, it would populate with the numeral 2; if C were selected, it would populate with the numeral 3; etc.

    So, we would have a combo box in the form, but it would not populate a table field with the combo box selections, but with values driven by the combo box selections.

    Is this possible?

    yes; the combobox (all active controls) has an 'AfterUpdate' event. You would put in vb code that would perform this task.

    the vanilla way that Access provides novices to this is a different approach - their path is to set up a 'lookup' field at the table level.

    However in your case you are wanting to do a translation from A to 1 - and so one must put in a little VB.

    Thanks for your quick reply. I think the lookup table approach is best for me (no VB skills).

    The task is actually to set membership levels for a Chamber of Commerce. So, my example simplified this - Associate = $X, Business = $X

    So I would build a table of amounts, then in the combo box how would I reference the lookup? (I hope I am on the right track)

    Well anyone designing a database needs a textbook. So be sure to purchase one in the version you are using, easily found at Amazon or any big box bookstore. Any textbook is going to cover setting up a lookup field in a table.

    The one additional hint to add about this is that Access likes to default the 'bound' column as the first column. So if your look up is of a table and you view: Title $

    It will default to putting in (bound) the Title.

    If your look up table has an autonumber key so that it is this:

    Key Title $

    It is going to want to enter the Key.

    One can change that after the fact - in the property of the lookup field...or be sure to set your look up table like this: $ Title

    and then it will enter the $ value into the field...

    I am using Access 2010

    I have a form (enter customer information). I have a customer table, state table, city table, and zip code table.

    On the form I have a state combo box and a city combo box. I want to select the state and from that selection I want the city combo box to be populated with all the cities from the state that was selected from the state combo box.

    I have a query that the following code has been entered into it:

    SELECT CityTbl.CityName, CityTbl.CityStateName, StatesTbl.StateName
    FROM [StatesTbl].StateName
    WHERE StateName = cboState;

    When I select the state the city is not being populated.

    In advanced, Thank you for you any help given.

    A combobox contains data that is valid when the form is opened.

    Therefore when you select a State; you must force the City combobox to requery.

    Hope this helps.
