Servo won't turn while accepting commands from an Arduino - Raspberry Pi Forums

in first post, i'm asking advice -

i'm attempting turn servo arduino when gets orders serial contribution, situation, console. have officially done engines , works fine when attempt servo doesn't move means. (an example - http://www.powerjackmotion.com/product- ... tor-range/ ) far have written -

#include <softwareservo.h>

softwareservo myservo;
int movemotor;
void setup() {
serial.begin(9600);
myservo.attach (10);
myservo.write(90);
}
void loop() {
movemotor = serial.read();
if (movemotor = 111) {
(int pos = 90; pos >=0; pos--) {
myservo.write(pos);
delay(15);
}
}
else if (movemotor = 99) {
(int pos = 90; pos <= 180; pos++) {
myservo.write(pos);
delay(15);
}
}
}

i'm powering servo remotely 9-volt battery , have made point associate ground of arduino, however, can't see whatever else fouled up.
appreciated.
in advance!

isn't question arduino forum or motor manufacturer or whoever wrote code?
