I am bringing in refund data from Shopify via an automation with webhook. When more than one item is returned, the webhook sends all of the subtotal values in a comma-separated list (see screenshot below). I’m trying to put this into a currency field in an automation, but that is causing the automation to fail when there is more than one item in the list. If I change the field type to single line text, the automation will work, but then I have to find a way to sum these values in a different field. The list of values could be one or many (up to 5+). Do you know of a formula that can accomplish summing the values in the string or do I have to have a script?

Thanks for all the help in advance!
