TransactionScopeOption.Suppress does not work

I have a transactionscope like this:

 using (TransactionScope tran = new TransactionScope())

                     catch (Exception ex)
                          //handle exception


In method1 I call a SP and catch any exceptions which I want to log and commit

So within the catch part of another try..catch within method1 I have the following code.

catch (Exception ex)

                        using (var scope = new TransactionScope(TransactionScopeOption.Suppress))
                            Conx.InsertLog( ex.Message, ex.StackTrace);

I understood that the second transactionscope should be unaffected by the ambient transcationscope...and when I step through the code errors are being logged. However they all seem to be rolled back by the ambient TransactionScope. What am I doing wrong??

Solved problem, I was using the same DB conx in both. When I used a new connection in second transaction it worked.
