Populating textboxes based on multiple combobox selections

[hannvis]

Hi all, I currently have a userform that has 4 comboboxes, all filtering from a table, with the last combobox being filtered to a single row match in the table. Once that match is made, textboxes are filled with the data contained in the adjacent row in the table.

I am using the below code to fill in these textboxes

Sub GetDataCBbased()

    Dim wo As Long, i As Integer, j As Integer, flag As Boolean

    If IsNumeric(UserForm1.ComboBox4.Value) Then
        flag = False
        i = 0
        wo = UserForm1.ComboBox4.Value

        Do While Cells(i + 1, 1).Value <> ""

            If Cells(i + 1, 1).Value = wo Then
                flag = True
                For j = 5 To 12
                    UserForm1.Controls("TextBox" & j).Value = Cells(i + 1, j).Value
                Next j
            End If

            i = i + 1

        Loop

        If flag = False Then
            For j = 5 To 12
                UserForm1.Controls("TextBox" & j).Value = ""
            Next j
        End If

    Else
        ClearForm
    End If

End Sub

This all works fine, but the search is only being constrained to the selection made in the final combobox, this would be fine however, that value is not unique in the table, so I am missing rows of data in the results of my UserForm. So my question is if I can constrain the search to all the combobox selections rather than just the last one.

Any assistance would be greatly appreciated as I've completely hit a roadblock with this. I attached the file below
