Why is my value empty?

There are 5 different fee structure in my worksheet.

Why is it that the FeeSt value is empty? If the Cell in Row 2, Column 1 contains the value "Split Fee", shouldn't the FeeSt value be "Split Fee"?

Sub feestructure()
Dim FeeSt As String
For X = 2 To 6
Worksheets("Customer Reference").Range("A" & X).Value = FeeSt
'Blah blah do something
Next
End Sub
