Question

I am having trouble getting a double to show up in my alert view. The string keeps showing up as 0 in the AlertView. Thanks in advance!

    double binRadius = [txtRadiusInches.text doubleValue] / 12 + [txtRadiusFeet.text doubleValue];
NSString *myString = [NSString stringWithFormat:@"%d", binRadius];

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Estimatated Amount"
                                                message:myString
                                               delegate:self
                                      cancelButtonTitle:@"Continue"
                                      otherButtonTitles:@"Clear All", nil];

[alert show];

%d (and %i) is the format specifier for integers (decimals). For floating point numbers you should use %f.
