RGB led lighting project code malfunction

hello all, thank helping me out. totally new arduino code (and answer problem) going simple. have tested hardware several times both multimeter , serial moniter. first serious project, , trying construct lighthouse. want light house turn on when light level low. want motor turn on , spin mirror around. trying make motor speed adjustable based on state of potentiometer. additional feature have able switch between solid white light , alternating colors. when ran code however, nothing whatsoever happened. observation had (and don't know if helps) realized led connected pin 13 dimly lit. offer me, newbie, appreciated.

here code:

int potentiometer=a2;
int swtch=a5;
int threshold=1000;
int photo=a0;
int blue=13;
int green=12;
int red=11;
int val=0;
int motor=9;

void setup(){
pinmode;(motor,output);
pinmode;(blue=output);
pinmode;(green=output);
pinmode;(red=output);

}
void loop(){
  val=analogread(photo); //checking light conditions//
int swtchstate=analogread(swtch);   //check switch//
  if(val<threshold && swtchstate>500){
    analogwrite(motor,potentiometer); //turns motor on if light conditions low// //sets motor speed based on potentiometer//
        digitalwrite;(blue,high);     //if switch on turn on white light//
      digitalwrite;(green,high);
      digitalwrite;(red,high);
    ;}
    else if(val<threshold && swtchstate<500){ //if switch turned offand light conditions low led alternate color//
     analogwrite(motor,potentiometer); //turns motor on if light conditions low// //sets motor speed based on potentiometer//
      digitalwrite;(blue=high); //blue//
      delay(100);
      digitalwrite;(blue=low); //green//
      digitalwrite;(green=high);
      delay(100);
      digitalwrite;(green=low); //red//
      digitalwrite;(red=high);
      delay(100);
      digitalwrite;(red=low); //teal//
      digitalwrite;(blue=high);
      digitalwrite;(green=high);
      delay(100);
      digitalwrite;(blue=low);//yellow//
      digitalwrite;(red=high);
      delay(100);
      digitalwrite;(blue=high); //purple//
   delay(100); }
   else{}}
   

code: [select]

digitalwrite;(blue=high); delete semi-colon after digitalwrite , correct syntax too.

similarly @ pinmode command syntax
