AWOL:
Is this implementation of the pullup code from CrossRoads correct?
Crossroad's original suggestion was correct.
Your mangling of it is too verbose.
See reply #3, particularly the word "or".
Sorry about that. It was late and I was busy with a tutorial on the pullups on the second part of CrossRoads' suggestion and didn't notice that I already implemented the first suggestion from him.

const int buttonPressPin = 2; //refers to the pin where the button is connected for user input
const int glassSensorPin = 3; //refers to a button that is depressed by the weight of a glass
const int relayOutPin = 13; //refers to the pin being used to trigger the relay
const int delayTime = 1250; //constant value assigned to delayTime, used to keep solenoid valve open

else

Rectified! (I hope)
