Reference field formula

[RebeccaJo1]

I can't figure out how to copy a formula we use for a reference number into a different custom field. When I copy and update the custom names it tells me that "Packaging Request Type is not a valid field in your system".  I'm not sure what that means? It's a custom field we have been using and looks the same as Tactic Type from the current formula.

Current formula:

CONCAT(LEFT({DE:Tactic Type},2),"_",IF(MONTH({DE:Final Files Due Date})>=8,RIGHT(YEAR({DE:Final Files Due Date}),2)+1,RIGHT(YEAR({DE:Final Files Due Date}),2)),"_",{referenceNumber})

Copied Formula:

CONCAT(LEFT({DE:Packing Request Type},2),"_",IF(MONTH({DE:Final Files Due to SUPPLIER})>=8,RIGHT(YEAR({DE:Final Files Due to SUPPLIER}),2)+1,RIGHT(YEAR({DE:Final Files Due to SUPPLIER}),2)),"_",{referenceNumber})

I always click on the field (separate window), and copy the field name from there and then paste into the calculation, if I'm having issues. That said, are you aware your copied formula says "packing request type" and that your error message says "packaging request type"?
