Update table with Multi-select list box

[Stewart]

I have a database with a tab control that has several pages in it (my
boss loves tabs for navigation). Each page has a list box based on a
category of training events that members of my office attend and the
box is based on a query that selects the training events for the tab
page's respective category. I select an item from the list, click a
button, and go to a form with a text box showing the name of the
training event I previously selected. On that form, I want to select
mutiple names of office members from a list box (already created and
source is the Office Roster table) and then click on a button to have
it update the training event record with the list of attendees I
selected. What is the best way to do this? I don't know how to write
VBA code but I am familiar with the editor.

Relevant Tables: Training Event, Office Roster, Training Category

Thanks in advance for your help.

' Newly selected rows will be added to the table, newly
cleared

On Error GoTo PROC_ERR

Else
If Not .Selected(iItem) Then

End If
Next iItem
End With
rs.Close
Set rs = Nothing
Set db = Nothing
Me.subAnimalCondition.Requery

PROC_EXIT:
Exit Sub

PROC_ERR:
MsgBox "Error " & Err.Number & " in cmdProcess_Click:" _
& vbCrLf & Err.Description
Resume PROC_EXIT

End Sub

Relevant Tables: Training Event, Office Roster, Training Category

AnimalCondition is your Training Event; the primary key of Office Roster is
AnimalID (though I hope you don't have too many animals as coworkers); and the
primary key of Training Category is my HealthIssueID.
