Serial.print will stop my other functions in my program

I’m doing an intro to programming and we are interfacing an Arduino board with a Frankenboard; using switches, LEDs, a potentiometer and an LDR.

I just finished programming my LEDs to correspond with certain switches, as well as an “if” statement to program the POT and LDR to turn on a LED (successfully). But once I try and serial.print the values of the LDR and POT, the rest of my programming for the switches/LEDs no longer work.

I’m assuming this is a very simple problem but I can’t seem to figure it out.

First thing I saw:

.
    else (Switch1 == 1); 
    {
.
.
.

(there's a lot of these...)

Two things wrong here: Can you see them?

Also, how are your switches wired? Can you show a wiring diagram?
