error compilling

when ever i try to compile this code i get the errors seen in the .jpg

#include <SoftwareServo.h>

SoftwareServo servo;
int potpin = 0;  
int val;

void setup()
{
  
  servo.attach(3);

}

void loop()
{
  val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023) 
  val = map(val, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180) 
  servo.write(val);                  // sets the servo position according to the scaled value 
  delay(15); 
  SoftwareServo::refresh();
}

Instead of wasting 235.3 Kb of disk on a screenshot of the error, how about copying and pasting it here?

How to use this forum

What's SoftwareServo? Where did you get it? How did you install it? More detail would be good.

I think you need

#include <Arduino.h>

thanks for the reply it seems that i can't copy the error message i don't know why i right click but the little box with the options does not show up. but what im trying to do is control a esc (electronic speed control) with a attiny45 but i was going to just run it with a nano but i got an error message i can't use servo because i plan on using the attiny once ever thing is working
here is a thread on running the attiny with software servo
http://forum.arduino.cc/index.php?topic=62912.0
but like i said im just trying to run it on the nano right now well i used verify i never tried to upload it the way i installed it was by using the sketch>import library>add library and i can see it at the bottom sketch>import library now so i guess it's installed right

and here is a link of a video to how to run an esc with software servo

im probably missing something simple because it's 3:45 in the morning
i have spent all day and night working on turning my 3d printer into a pcb etcher

the place i got it from
http://playground.arduino.cc/ComponentLib/Servo

i tried adding #include <Arduino.h> but it does the same thing
