AA360 Interactive Form

Hi everyone, 

Is there a way for me to build an interactive form with a dropdown that can enable user’s to select multiple options within the dropdown? I’ve tried this by making use of a checkbox with the various options a user can select, however I’m struggling with reading the actual value/name of the checkboxes selection as I need to store it in a variable to be used at a later stage. 
 

Is there a way I can go about this on the interactive form? Below is the checkbox list I’ve created and added into the form and I need to get the value eg: SRV00871
 

Kind regards,
