Trying to add a combo and list box that pulls from seperate tables and updates a table

Table 1 - Employee Data
Table 2 - Skills Data
Table 3 - Resources

Objective is:
Step 1: Pull employee information from Table 1 by Employee ID #.  This Combo box will auto populate my form while updating Table 3 on the back end.  >> This works with simple code (see below)

------------------------------------------------------------------------------------------
Code that populates Table 3 for Step 1:
Private Sub cboLogin_Change()

Me.txtFirst.Value = Me.cboLogin.Column(1)
Me.txtLast.Value = Me.cboLogin.Column(2)
Me.txtFull_Name.Value = Me.cboLogin.Column(3)
Me.txtEmail.Value = Me.cboLogin.Column(4)

End Sub
----------------------------------------------------------------------------

Step 2:  Skills section pulls from Table 2, must be able to multi-select data (Access, SQL, VB) and update table 3 in the skills field.

I can create a combo box with multi-select capabilites, but this does not update Table 3.  The skills field is set to text.

What am I missing?
