Sendmail to picklist

Sendmail to picklist

Hi,
I'm unable to find an help in this forum and in sampleapps. I have formB with list of employee and formA with subform for uploaded document and a picklist lookup field with email of employee showed as name of employee. 
I need to do the simply action to send in attachment (as link) the uploaded doc to the employee selected in the picklist. I look for it in the iterate  https://help.creator.zoho.com/Iterate-Records-in-a-Form.html and  https://help.creator.zoho.com/Iterate-Data-in-Radio-buttons-and-Checkboxes.html and for each  https://help.creator.zoho.com/for-each-record-in-form.html and iterate data in Radio buttons  https://help.creator.zoho.com/Iterate-Data-in-Radio-buttons-and-Checkboxes.html, but I still cannot produce the correct strip that allow sendmail.
Any help?
Thanks a lot.
