Error When Calling Stored Procedure

I am trying to execute a store procedure from ASP/VB but it fails with the message:
Incorrect syntax near 'InitProject'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near 'InitProject'.

Source Error:





Line 24: cmd.Parameters("@ProjectId").Value = 3
Line 25: cn.Open()
Line 26: cmd.ExecuteNonQuery()
Line 27: cn.Close()
Line 28: End Sub

Here is my code:

        'Execute the InitProject stored procedure
        'Create the connection from the string in the web.config file
        Dim cn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("SMARTConnectionString").ConnectionString)
        'I want to execute InitProject stored procedure
        Dim cmd As SqlCommand = New SqlCommand("InitProject", cn)
        'With the parameter @ProjectId = 3
        cmd.Parameters.Add(New SqlParameter("@ProjectId", Data.SqlDbType.Int))
        cmd.Parameters("@ProjectId").Direction = Data.ParameterDirection.Input
        cmd.Parameters("@ProjectId").Value = 3
        cn.Open()
        'But this fails
        cmd.ExecuteNonQuery()
        cn.Close()


And my stored procedure is defined as:

[dbo].[InitProject] @ProjectId int
 -- Add the parameters for the stored procedure here
AS
BEGIN
 -- SET NOCOUNT ON added to prevent extra result sets from
 -- interfering with SELECT statements.
 SET NOCOUNT ON;

    -- Insert statements for procedure here
insert into MATERIAL ( PROJECT_ID, SECTION_ID, CATEGORY_ID, ROOM_ID, ITEM_ID )
select @ProjectId, SECTION_ID, CATEGORY_ID, ROOM_ID, ITEM_ID
from MATERIAL_TEMPLATE
END

 The store procedure works fine when I do

exec InitProject 3

in sql query.
