How do i set the value for a service parameter in javascript.

How do i use Javascript to update a service's parameter in the Before send event ?

To explain, I have 3 user text inputs which i can access and get a popup showing the correct data as follows...

alert("Name: " + Apperyio('txtName').val() + "\n" + "Company: " + Apperyio('txtCompany').val() + "\n" + "Phone: " + Apperyio('txtPhone').val());

Instead of a popup, I would like to get that 1 string into the email message body. The sendgrid service parameter is "text"
