Floor Pivot Point Question!!

[dscurry]

Can anyone assist me? I've downloaded the floor pivot indicator and would like to modify it slightly. I would like to draw another line between the midpoints and support and midpoints and resistance. I've tried to modify the code using the following:

if(trailing)
{
FiftyTS14.Set((FiftyR54+r4)*.50);
FiftyTS13.Set((FiftyR54+r3)*.50);
FiftyTS12.Set((FiftyR43+r3)*.50);
FiftyTS11.Set((FiftyR43+r2)*.50);
FiftyTS10.Set((FiftyR32+r2)*.50);
FiftyTS9.Set((FiftyR32+r1)*.50);
FiftyTS8.Set((FiftyR21+r1)*.50);
FiftyTS7.Set((FiftyR21+pp)*.50);
FiftyTS6.Set((FiftyR1PP+pp)*.50);
FiftyTS5.Set((FiftyR1PP+s1)*.50);
FiftyTS4.Set((FiftyPPS1+s1)*.50);
FiftyTS3.Set((FiftyPPS1+s2)*.50);
FiftyTS2.Set((FiftyS12+s2)*.50);
FiftyTS1.Set((FiftyS12+s3)*.50);
FiftyTS1B.Set((FiftyS23+s3)*.50);
FiftyTS1A.Set((fiftyS23+s4)*.50);
}

but I keep getting error codes indicating "+" operator not allowed in 'bool'. I've modified it, but it still does not work! Any suggestions would be greatly appreciated!!!!!!

Please ensure you declare needed variables for holding values as doubles here and then you should be able to add / subtract as needed.
