Hello, I am trying to add a custom hyperlink field that is a calculated value to one of my transaction forms. The hyperlink is <a href="https://system.netsuite.com/app/accounting/transactions/purchord.nl?id={createdfrom.internalid}"> Purchase Order link</a>. I keep on getting the error Your formula has an error in it. It could resolve to the wrong datatype, use an unknown function, or have a syntax error. Please go back, correct the formula, and re-submit. What am I doing wrong
