Hi @tyguyps2
Help links for using Storage: https://zapier.com/apps/storage/integrations#help
You probably want to push each Contact ID value onto the List.
You can either have 3 Storage steps in the Zap.
Or you can delimit those and push on the List once as 1 value.
e.g. Value = ID|ID|ID
Hi there, @tyguyps2 
Did Troy’s suggestion of using multiple Storage actions or combining the different values together into the list do the trick?
Keen to make sure you’re all set, so please let us know if you have any questions or need any help!
Thanks! I no longer need to do this, so I didn’t test out his suggestion.
No worries, @tyguyps2! Thanks for letting me know.
If anything changes and you decide to give it a try or you need help with anything else down the line, feel free to reach out!
Since Troy’s suggestion is likely the best option for now, I’ll go ahead and mark it as the best answer in case it helps others who come across this thread—thanks @Troy Tessalone! 🧡
