Newbie :) 'if' help

hi guys, got self arduino other day
ive been going through beginner tutorials , sketches , learning basics, started learning 'if' statements , thought try , use 1 turn 2 led's 1 , off modifying blink example, example had 1 led running normal blink used second led in if statement opposite of led 1 does. reason wont work, obvious, led 1 blinks fine led 2 stays off. ill add sketch sorry if messy, onty had 3 days
thanks!
(sorry dont know how add sketch properly)

int ledpin1 =  5;  
int ledpin2 = 7;


void setup()   {                

 pinmode(ledpin1, output);  
pinmode(ledpin2, output);  
}

void loop()                    
{
 int ledpin1value = digitalread(ledpin1);
 digitalwrite(ledpin1, high);  
 delay(1000);                  
 digitalwrite(ledpin1, low);  
delay(1000);
 
if (ledpin1value = high) {
 digitalwrite(ledpin2, low);
}
else {
  digitalwrite(ledpin2, high);

}
 
 
}

i understand trying buts allot easier this.

btw code added using # button in message edit field.

code: [select]

int ledpin1 =  5;  
int ledpin2 = 7;


void setup()   {                

pinmode(ledpin1, output);  
pinmode(ledpin2, output);  
}

void loop()                    
{
int ledpin1value = digitalread(ledpin1);
digitalwrite(ledpin1, high);
digitalwrite(ledpin2, low);  
delay(1000);                  
digitalwrite(ledpin1, low);
digitalwrite(ledpin2, high);

delay(1000);

}

but problem code need '==' not 1 '='.
