Not outputting calculated data

[Tom Mordon]

Hello,
I'm trying to get my android app to output the data after the calculate button is clicked. The application boots correctly and allows me to type in the times to be calculated but once I hit the button it says error unable .... and does not not work. I know the calculation code works correctly so the problem is somewhere in Android code I think. Any help is appreciated. Any thoughts as to why the calculate button is not working properly?
Thanks

There is just too much code here to analyze quickly. Can you post a stack trace so we can zero in on the problematic parts ?
