I cant seem to find the problem in this script that I have written. The script makes the first temperature go all funky.
Code:

int16_t rawADCvalue2; // The is where we store the value we receive from the ADS1115
//int16_t readADC_Differential_2_3
float scalefactor = 0.1875F; // This is the scale factor for the default +/- 6.144 Volt Range we will use
float volts = 0.0; // The result of applying the scale factor to the raw value
float amps = 0.0;
