Passing input select values to plugin within controller


I need some assistance getting over the hump here. I can’t figure out how to pass the values from the input select to a controller. The purpose of this little app is to build a customized email. Simply input the values, select the Send Mail button and the native iOS email framework is presented. The basic functionality works with the code I’ve included but I want to replace the hard-coded values for Subject, Body, etc with values from the input screen.

Thank you in advance for your input and assistance
