I set up a workflow to send an acknowledge e-mail to the submitter of a form plus 1 secondary contact - both e-mail contacts are specified in separate fields and are selected via people pickers (column set as Person or Group) and the workflow was working fine, but I've now had to change one of the contact fields to allow multiple contact selections and the workflow no longer runs - it shows as 'suspended' with the error reason showing the value results for the secondary contact field cannot be read as type 'String'. I need to allow for people to put multiple contacts in the Secondary Contact field and the e-mail to be sent to all, does anyone know of a way around this without having to add numerous separate contact fields on the form? Thanks for your help.
