Select Count causes system error

[indydavid32]

This is my code.

Dim cn2 As New SqlClient.SqlConnection()
cn2.ConnectionString = "Integrated Security=True;" & _
        "Data Source=Brutus;Initial Catalog=Problem Tracking;" & _
        "user id=user;password=pass;"
cn2.Open()
Dim commSQL2 As New SqlClient.SqlCommand()
commSQL2.Connection = cn2
Dim datRead2 As SqlClient.SqlDataReader
commSQL2.CommandText = "Select Count(Store Number) As Exp1 From Stores Order By [Store Number]"
datRead2 = commSQL2.ExecuteReader

This causes the following error message:
An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll

Additional information: System error.

I tried it with a regular Select command like this.

commSQL2.CommandText = "Select [Store Number] From Stores Order By [Store Number]"

This worked fine.

Anyone have any ideas why the select count statement is not working?

Thanks
