VB code for Data Population & Creating Cascade Combo Boxes

Data Entry FormQueryComboBox Data PropertiesComboBox EventPropertiesI have a data entry form in ACCESS program (someone else created) and I can't find VB code that populates the first name in the first name field when last name in the last name/first name drop down/combo box is selected.

Ultimately I need  to create two drop down boxes - (1) last name only and (2) once the user selects the last name and taps over to first name combo box, it will display first names only with the last name selected in the last name combo box.

But I can't even figure out where to find VB code on the current form where the first name is automatically populated once the last name is selected.

You can use the AfterUPdate event of the first combo:

Sub YourFirstCombo After_UPdate()
  Me.YourSecondCombo.RowSource = "SELECT Emp_ID, First_Name FROM Emploee WHERE Last_Name='" & Me.YourFirstCombo.Column(1) & "'"
End Sub

I'm not sure of the actual Column to reference in YourFirstCombo ... the code above refers to the 2nd combo. If you need to refer to the 3rd column, use Me.YourFirstCombo.Column(2)

Thanks for the combo box suggestions above.

Can you see where I might be able to find the VB code that populates first name into the first name field (at this point, first name field is NOT a combo box. It is just text field)

I'm not sure what you're asking. The FirstName field could be "bound" to a control, or it could be filled through code action somewhere. The images you've given us aren't sufficient for us to tell this, and since we have no idea how the form is used it's impossible for us to say.

You could perhaps upload a copy of your database with specific instructions on how to recreate the issue. If you do this, be sure to remove any sensitive information first.
