If you have a Multi-Select type workflow attribute called “Check All That Apply” with the attribute key of {reason} and you have the following multi-select values:
0^I'm New Here
1^I'm not New Here
If you wanted to preselect ‘I’m New Here’ when a person visits the page, you would append ?reason=0
to your URL.
Example: My.CedarCreek.tv/page/###?reason=0
