Print via Combo Box Dropdown List

I have the following code for printing but need to change the "input" to depend on a combo box instead. I have the combo box built with a named range as the row source but am unsure how to link that combo box dropdown selection to fill in for the autofilter so that it prints the desired manager's employee information. I haven't been able to find a similar situation with a combo box being linked to a print action. Please let me know if this does not make sense and I'll try and explain it another way! Thank you!

Sub Dept_BGT_Print()
Dim Sel_Manager As String
'Specify headers to be repeated at the top
With ActiveSheet.PageSetup
        .PrintTitleRows = "$5:$9"
        .PrintTitleColumns = "$B:$M"
End With

'Manager selection through simple Inputbox
 Sel_Manager = InputBox("Which manager?")
'Insert autofilter for worksheet
Cells.Select
Selection.AutoFilter
'Select manager defined in inputbox
ActiveSheet.Range("B14", Range("M14").End(xlDown)).AutoFilter Field:=1, Criteria1:=Sel_Manager
 'Select range to be printed and specify manager in filename
ActiveSheet.Range("B14", Range("M14").End(xlDown)).Select

Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
"Employee Information.pdf", Quality:=xlQualityStandard, _
IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:=True

 'remove autofilter
  ActiveSheet.ShowAllData
End Sub

Issue solved

How was the problem corrected ? So all of us can share in the solution.

Thanks !
