I have a form with a checkbox field with multiple options with an abbreviation as each label's value. For example, the label "Field Operating Guideline" has a value of "FOG". I then have a workflow that assigns the checkbox values selected to a multivalue token and then writes that token to SQL. The problem I am running into is that the checkbox label is what is written to SQL, not the value. How can I get the value to write to SQL instead of the label? Screenshots and details are below.

The user selects checkbox values in Forms:

The completed instance shows the abbreviation as the value for the variable:

I have the variable selected in the Retrieve Business Process Variables activity:

Then it's assigned to the multivalue token

Then I have an Insert Data activity to write the token to SQL

SQL shows the selected label, not the abbreviation value.
