MainActivty.java file which allows user to input data into fields, and then they hit 1 button "calculate" and it manipulates all the data and displays it on the Results.java page. (the NEXT button at top was a test to see if I could even load the Results page, which no, clicking the NEXT button just crashes the app, and the calculate button is not even clickable)

MainActivity.java

MainActivity.java continued

Does anyone have any idea why my calculate button is not working on my app? I am only allowed to post 2 links so if you need another picture let me know.

your onButtonCalculate() doesn't call add 

android:onClick="onButtonCalculate"

In your XML code
