error too few arguerment

Projects Programming
1

In the above code line "analogWrite(motp2=ir2var);" is highlighted.cant understand the error.

2

analogWrite(motp2=ir2var);

3

What was the error? Oh, never mind... too few arguments. analogWrite takes 2 arguments, you only gave it one.

Thanks aarg. I am sorry if I did not mention the error. I am giving below the code in the function in which this error appeared. I am not sure if this is the way to provide the code in brief although I have read the entire method to use the forum.

void movefwd(){
int ir1 = A0;
int ir2 = A1;
int motf1 = 33;
int motr1 = 35;
int motf2 = 37;
int motr2 = 39;
int motp1 = 41;
int motp2 = 43;
int ir1var;
int ir2var;
ir1var=255;
ir2var=255;
analogWrite(motr1=ir1var);
analogWrite(motr2=ir2var);
ir1var=0;
ir2var=0;
analogWrite(motf1=ir1var);
analogWrite(motf2=ir2var);
ir1var=ir1/4;
ir2var=ir2/4;
analogWrite(motp1=ir1var);
analogWrite(motp2=ir2var);
  }

What other argument can I give?

Look at reply #3.

Thanks aarg and Delta_G. Reading the link mentioned by Delta_G cleared my doubt and verification/compile error.
