void value not ignored as it ought to be

Using Arduino Programming Questions

seem to have a new problem :confused: this one really is stumping me even after reading about how to use these, since its using a library it makes it confusing. Seems like capacitive sensor library makes you set the objects value to a function in the library, so I am not sure how to make this work.

I need to populate an array of objects I would expect it to work how I have it here in the setup function:

   CapacitiveSensor cs_sensor[numberOfSensors];
   
   for(int i = 0; i < numberOfSensors; i++){
     cs_sensor[i] = CapacitiveSensor(capSenseSend,sensorPin[i]);
   }

so I can later set the current reading using this in the loop:

void setSensorValue(){
  for(int i = 0; i < numberOfSensors; i++){
    letters[i].setCurrentReading(cs_sensor[i].capacitiveSensor(50));  
  }
}

but no luck.
