I will assume that Combobox1 is located on a Userform. If that is the case,
put this in the Userforms Intialize Event. Hope this helps! If so, let me
know, click "YES" below.

Private Sub UserForm_Initialize()

Select Case ActiveWorkbook.Worksheets("FR Launch Sheet").Range("B3").Value

Case Is = "Sat"
Me.ComboBox1.RowSource = "'Routes'!$E$2:$E$61"
Case Is = "Sun"
Me.ComboBox1.RowSource = "'Routes'!$H$2:$H$61"
Case Else
Me.ComboBox1.RowSource = "'Routes'!$B$2:$B$61"
End Select

End Sub

Is it possible to set the RowSource for a ComboBox based on a condition?

For ComboBox1 I would like to set the RowSource as follows:

If ActiveWorkbook.Worksheets("FR Launch Sheet").Range("B3") = Sat then
Rowsource would be 'Routes'!$E$2:$E$61

If ActiveWorkbook.Worksheets("FR Launch Sheet").Range("B3") = Sun then
Rowsource would be 'Routes'!$H$2:$H$61

If ActiveWorkbook.Worksheets("FR Launch Sheet").Range("B3") did not equal
Sat or Sun then Rowsource would be 'Routes'!$B$2:$B$61
