Field variable, unstored

[chrisknight55]

Can an input field store in a defined variable, or must a field always store in a table?

Rather than add a new record and have to delete that record if the transaction is abandoned by the user, I'd like to have the user input a value to a variable then add a new record and transfer the variable to a field only if the user commits to the transaction.

Use a global field:
