I need to use a comma in my value list, but Marketo uses the comma as the break between different values.
Select One, Not at this time, Yes, within 30 days, Yes, within 60 days
Begin your value list with "\|||\" and use "|||" instead of a comma between each value.
\|||\Select One|||Not at this time|||Yes, within 30 days|||Yes, within 60 days
Nice work! You can now use commas in the text of your Value List.
