Excel 2010 – Call a subroutine from a macro

I wrote (borrowed) some simple VB to take a variable from a text box in an Excel sheet and perform a search on the same sheet.  It works fine when I used a command button to run it, but I want to run it from a macro and can’t seem to get it to work.
The command buttons look old fashon and cluncky as compared to the shapes that can be created with
Excel 2010.  The shapes can only be used as buttons to run macros, however. So I want a macro to call the code to do the search.

(I saved the file down to Excel 2003 since not everyone has 2010)

This is in Module 1
Sub RoundedRectangle2_Click()
     Call FindProject
   'Application.Run "FindProject"
End Sub

This is in Sheet1 module
Public Sub CommandButton1_Click()
   ‘ This runs fine from the Command button

           Dim strFindWhat As String
           strFindWhat = TextBox1.Text
           On Error GoTo ErrorMessage

    Cells.Find(What:=strFindWhat, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
        :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
        False).Select
    Exit Sub
ErrorMessage:
                  MsgBox ("The data you are searching for does not exist")

End Sub

Private Sub FindProject()
  ‘ This code was copied from above and I try use a macro to call this sub – it doesn’t work

           Dim strFindWhat As String
           strFindWhat = TextBox1.Text
           On Error GoTo ErrorMessage

    Cells.Find(What:=strFindWhat, After:=ActiveCell, LookIn:=xlFormulas, LookAt _
        :=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
        False).Select
    Exit Sub
ErrorMessage:
                  MsgBox ("The data you are searching for does not exist")

End
