Macro to copy pages from other tabs fails today,

[dmcgov]

i used this code yesterday. all it is supposed to do is cycle through some worksheets and copy to a master page. the thing is that yesterday it worked, today it doesnt. any help is appreciated

Sub dmcgov()
For Each ws In ThisWorkbook.Worksheets
    Set c = Sheets("Formulas").Range("K19:K148").Find(ws.Name, lookat:=xlWhole)
    If Not c Is Nothing Then
    Sheets(c.Value).Select
    Range("B2:H324").Select
    Selection.Copy
    Sheets("Estimating1").Select
    Range("C2").Select
    Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks _
        :=False, Transpose:=False
    End If
Next
End Sub

so the range k:19 to k:148 are the names of the tabs, like A,B,C,D,...X,Y,Z,AA,BB,CC...ZZZZZ that i would like to cycle through, the sheets(c.value) should render A.value, the range is what i am copying, and estimating1 is the sheet i would like to do a paste value to. does this help?
