adding ten fields (different fees) to a display field on a form RRS feed

  • Question

  • I have ten different fees on a form for which I want to show a running total in a text field that is not part of the table that the ten fields come from.

    I have tried several tactics 

    1. the running total field contains "=CurrRunningSum()" a function that adds each field 

    2. the running total is updated by a Sub that adds each field and is prompted by the exit event of each of the ten fields on the form.

    Either of these is invoked in the Form_Current event as well.

    Each approach has deficiencies.

    The first seems to work only on saved records and not on new ones which suggests that I am not referencing the fields appropriately on a new record.  I have tried several ways of referencing the fields including



    me.fieldname (no brackets, with underscores for spaces.)

    I have also protected against null entries and datatype differences with a function called "Makeval" that converts each field to a number.

    This seems like it should be easier than it has turned out to be.

    Any good references on doing something like this will be appreciated.

  • I successfully got around whatever was fighting me.  Instead of using the field names, i gave each of them a tag called "Fees."  Then I referenced them  in a subroutine using a "For Each ctrl in Me.Controls" loop that operated only when the control had that tag.  I invoked the subroutine at the Form)Current Event and at the Exit event of each of the fee fields.  This finally worked for both existing records and new records.
