Multiple Selection and use in Workflow.

Hi there,

I have a list with a multiple selection check box with a some city's listed. Each city will relate to an email address for that particular location and is defined in a workflow.

For each location I setup a workflow variable (i.e. If Perth is selected set email to perth@xxxxx.com). I now need it so multiple offices can be selected (so if Perth and Sydney are selected then set the email to go to perth@xxxxx.com and sydney@xxxxx.com).

Can anyone assist with this?

Thanks,
Ben
