hi guys..

can anyone tell me what might be the error at the following code ?

public void getCounterValue(string countername,string tablename,string email)
{


SqlConnection conn = null;
SqlDataReader reader = null;

int result = 0;

try
{

conn = new SqlConnection("Server=(local);Integrated security=SSPI;database=halkdanis");
conn.Open();
SqlCommand cmd = new SqlCommand("select @ctr from @table where @mail = @mail", conn);

SqlParameter param = new SqlParameter();
param.ParameterName = "@ctr";
param.Value = countername;

SqlParameter param2 = new SqlParameter();
param2.ParameterName = "@table";
param2.Value = tablename;

SqlParameter param3 = new SqlParameter();
param3.ParameterName = "@mail";
param3.Value = email;


cmd.Parameters.Add(param);
cmd.Parameters.Add(param2);
cmd.Parameters.Add(param3);


reader = cmd.ExecuteReader();


while(reader.Read())
{
result = Convert.ToInt32(reader[0]);
}
}

catch(Exception x)
{
MessageBox.Show(x.ToString());
}
finally
{
reader.Close();
conn.Close();

}

}

it throws the exception @table doesn`t have a value,

but it has the value tablename from the method construction..

any thougts ?

thx !
