Cannot send notification to many people

Hello,

I've designed a workflow to check the expiry date of some documents, and send a notification to the person/people assigned to the ones that will expire soon.
In my workflow, I have a variable(V1) that take the assigned to information, and then I put it on the "To" field to send a notification.

This is working fine when I have only one person in the Assigned to field, so I've introduced another variable (v2)=replace(cstr(GV_V1),",","; "), where I replace "," with ";" and then I put it on the "To" field, but this is not working.

Any ideas to make it work please?

Thank you in advance.
Regards
