im getting following error:

"a first chance exception of type 'system.data.sqlclient.sqlexception' occurred in system.data.dll additional information: incorrect syntax near ')'. if there handler exception, program may safely continued."

is syntax? cant figure out, can tell doing wrong?

        private void button2_click(object sender, eventargs e)     {         messagebox.show("a atualizar dados...");         bool check = true;                 {             string connectionstring = @"data source=.\wintouch;initial catalog=bbl;user id=sa;password=pa$$w0rd";             string querystring = string.empty;             using (sqlconnection connection = new sqlconnection(connectionstring))             {                 connection.open();                 querystring = "update  wgcdoccab set merc1 = merc1/2 numdoc = (select max(numdoc) wgcdoccab serie ='1' , tipodoc ='fss' , contribuinte ='999999990' ,  datadoc = convert(varchar(10),(dateadd(dd, -1, getdate())), 120))";                 sqlcommand command = new sqlcommand(querystring, connection);                 command.executenonquery();                 connection.close();             }             using (sqlconnection connection = new sqlconnection(connectionstring))             {                 connection.open();                  querystring = "select max(numdoc) wgcdoccab serie ='1' , tipodoc ='fss' , contribuinte ='999999990' , datadoc = convert(varchar(10),(dateadd(dd, -1, getdate())), 120))";                 using (sqlcommand command = new sqlcommand(querystring, connection))                 using (sqldatareader reader = command.executereader())                 {                     if (reader.hasrows)                     {                          check = true;                      }                     else                     {                         check = false;                         messagebox.show("dados atualizados com sucesso");                     }                     command.connection.close();                 }             }         }         while (check);

check sql statements. line has many parentheses:

querystring = "select max(numdoc) wgcdoccab serie ='1' , tipodoc ='fss' , contribuinte ='999999990' , datadoc = convert(varchar(10),(dateadd(dd, -1, getdate())), 120))";
