Arduino compile error

[AndrewJPratt]

I took screenshots of the errors I'm getting in Arduino. The code is below the screenshots (sorry if the formatting is bad. I'm new to this site and the code is pretty long). The error comes at the line: bVal = blynk_r; Anyone know what they mean and the solution(s)? My file name is Capstone:
