i have a data entry form to where the user selects a Customer from a drop down. data source is a query from View on sql back-end. the user selects the customer and several fields on form will auto-fill from this data. I want a message box to appear when a credit limit field reaches a criteria. anyhow i am noticing two things. when testing other fields it seems to work (as far as vba code for msgbox). but when trying on an 'auto-filled' field it doesn't. when trying on an unbound auto-filled text box it doesn't. how do i get this to work? the field in question is an unbound text box that is one of the columns from the underlying datasource query. thanks.
