List consecutive days?

Greetings,

Ive been a member for some time and have found answers to all my past needs, so this is a good time to say Thank You!


Now, I havent been able to create a formula that fills my needs this time.

I have a list that has a column with a date and a column with a Error, I need to have some way of viewing whenever a Error is consecutive to a date the catch? well its Monday to Saturday and probably Networkdays.intl might be the way to go with some way of list, but im not sure.

Would you give me a hand? Attached a light copy of a list
