"the operation current state transaction" blunder transaction scope

i am removing following blunder i try stored way contains name statement:

the operation current state transaction

here structure calls:

public vacant myaddupdatemethod()
{

    controlling (transactionscope range = new transactionscope(transactionscopeoption.requiresnew))
    {
        using(sqlserver sql = new sqlserver(this.m_connstring))
        {
            //do initial supplement transform statement

            //do name matter sp
            bool doesrecordexist = this.selectstatementcall(id)
        }
    }
}

public bool selectstatementcall(system.guid id)
{
    using(sqlserver sql = new sqlserver(this.m_connstring)) //breaks line
    {
        //create parameters
        //
    }
}

is problem me formulating another tie same database within transaction?
