Hello SF community,

I'm new to flows and the process builder, and I'm trying to achieve the following:
Opportunity stage is anything other than closed/won, update "custom field" on contact role AND update 'custom field' on the contact roles' related contact record. 

i've found a similar topic posted here, but the screen shots on the topic only got me so far. 

Is there anyone that is willing to help out? Thanks in advance!
