i dont understand what actually the problem. i dont find any issue with the codes,it complied succesfully but cant upload to the uno

im uploading my code below

int control=7; // PIN FOR SWITCH CONTROL

int out1=8; // PIN FOR RED LIGHT
int out2=9; // PIN FOR GREEN LED

void setup(){
pinMode(control,INPUT); // INITIALISE INPUT PIN
pinMode(out1,OUTPUT); // INITIALISE OUTPUT PIN
pinMode(out2,OUTPUT); // INITIALISE OUTPUT PIN

}

void loop()
{
digitalWrite(out1,HIGH); // RED LED IN HIGH MODE BY DEFAULT
int val=digitalRead(control); // READ THE VALUE FROM THE SWITCH CONTROL PIN

if (val=HIGH) // TO GLOW GREEN LED WHEN THE CONTROL OF SWITCH IS HIGH
{
digitalWrite(out1,LOW);
digitalWrite(out2,HIGH);
}

}

if (val=HIGH)That's going to cause you trouble when you do get it to upload.
