I have a form to upload PDF files to ZOHO Creator

I have another form with client name, address and email address

I have a 3rd form that does a lookup on the client name to get their email address, and capture further information about that client

Is it possile to be able to select a document (from a browse or drop down list) previously uploaded and stored in ZOHO Creator and attach that document to an email to the clients email (from the lookup field) when the SUBMIT button is clicked on the form?
