Welcome to the community @valeria1802 

A great question and a head scratcher as Klaviyo doesn’t natively support chaining flows!

I think I’ve come up with a solution to your use-case but please review my logic. It’s a lengthy description and looks complicated, so please bear with me.

If others on here have a simplified approach, I’d love to hear it!

Approach

• Tag profiles using a custom property called guides_downloaded which is a list data-type so it can hold many values (for each guide).
• On a guideA form submission, set guide_downloaded to the value guideA_start. On a guideB form submission, set guide_downloaded to the value guideB_start
• Create two segments - one for guideA and one for guideB - based on the custom properties. Let’s call these guideA_in_flow and guideB_in_flow. Example guideA_in_flow segment below for a guideA form submission. Swap A’s to ‘B’s for the guideB segment
• Create two flows triggered by new members to these segments: guideA_flow and guideB_flow. The last step in each flow will update the guides_downloaded custom property.For the guideA flow remove the value guideA_start and add the value  guideA_end. For the guideB flow remove the value guideB_start and add the value guideB_end. This tags their profile as having completed the respective flows 

Let’s see how this would work with the possible scenarios:

Contact downloads only guideA

• form submission sets guide_downloaded to o“guideA_start”]. Brackets and quotes are how a list is stored in Klaviyo
• Contact is added to the guideA_in_flow segment because guide_downloaded contains guideA_start (true) AND (does not contain guideB_start (true) OR contains guideB_end (false)  
• Contact moves through the flow and at the last step - an update custom property - the value of the guides_downloaded removes e“guideA_start”] and adds n“guideA_end”] . The update means they are removed from the guideA_in_flow segment.
• All the above is similar for a contact who only downloads guideB 

Contact downloads guideA, completes the flow and then downloads guideB

• Form submission adds guideB_start to guide_downloaded so it becomes n“guideA_end”,“guideB_start”]. 
• Contact is added to guideB_in_flow segment because guides_downloaded contains guideB_start (true) AND (guides_downloaded doesn’t contain guideA_start (true as it was updated to guideA_end when they exited the A flow) OR guides_downloaded contains guideB_end (false))
• Contact moves through the flow and at the last step - an update custom property - the value of the guides_downloaded removes a“guideB_start”] and adds “guideB_end”] . The update means they are removed from the guideB_in_flow segment.
• All the above is similar for a contact who completes the guideB flow first then starts the guideA flow

Contact downloads guideA and then downloads guideB while still in the A flow

• Form submission adds guideB_start to guide_downloaded so it becomes r“guideA_start”,“guideB_start”]. 
• Contact does NOT enter guideB_in_flow segment (and therefore not the guideB flow) because guides_downloaded contains guideB_start (true) AND (guides_downloaded doesn’t contain guideA_start (false) OR guides_downloaded contains guideA_end (false))
• The contact will only enter the guideB flow when they are added to the guideB_in_flow segment. That will occur when they’ve completed the GuideA flow i.e guides_downloaded contains guideB_start (true) AND (guides_downloaded doesn’t contain guideA_start (true as it was updated to guideA_end when they exited the A flow) OR guides_downloaded contains guideA_end (true))

Phew! I think I will work, but please check my thinking and test!

Hi @valeria1802 

I have responded with a (lengthy) solution, but for some reason, it’s going into moderation! I am unable to to resubmit it!

@Taylor Tarpley @stephen.trumble - any reason why it’s been flagged?

Thanks

Andy

Exactly 

Hello @bluesnapper I can't read the whole solution. Maybe you can send it again or it should appear after moderation? Thank you so much for your help!

Hi @valeria1802 

I was finally able to post it! Must’ve been a forum glitch
