How to send multiple emails via a look-up

How to send multiple emails via a look-up

Hi,

When I press submit I want to send emails to whom I have selected in a look-up in my form. The look-up refers to a list of customers email-adresses. 

When I try to do this in script I get the following error message " Error in statement at line number 1  Email Address cannot be 'STRINGLIST'" Why can't i use a sting list for sending emails. How do I do instead?

Thanks!
