Exception handling variable pass to another flow if error found

Hi all,
I have sequence1.xaml and sequence.xaml
So basically in sequence xaml I got selector exception so in try I create exceptionfound variable and assign value as exception.tostring
Then in if condition I put exceptionfound is nothing then excecute sequence1.xaml but aevwn if error found it goes in then.so how to pass exception variable from one invoke code to another.
