how count nr of "error" on step and adapt the action

Hello,

I don’t find a working solution to setup a chain where we need to act when error occurs.

This chain has 8 steps. And we can consider that we have 4 blocks of 2 steps.

Depend on what step in a block ends with error the next action should be different.

Below a summary table where have been described the required actions :

• 1/ means step failed the 1^st time
• 2/ means step failed the 2^nd time

Depend if 1/ or 2/ the next action should be different.

Any idea how design these conditions ?

Kind regards,

Delphine
