Regex on a Lookup Table value?

[Jamie Gordon]

I'm trying to run a regex using match() on a Lookup Table value. Here my code

{{YaypayParams.get("longInvoice").match(".*^(C|CI|CID)-\d{1,10}$.*)}}

This code produces an error. Can this work?

Hi @Jamie Gordon 

What are you trying to achieve with the rule?

If you could provide detail on the wider rule itself also (esp. the Lookup table) - that'd be very useful :)
