LED +Servo misbehaving w/ Adafruit MP3 shield attached

hello,

i'm new coding arduino, , have been running odd problem project i'm building. 1 button push, trying to:

• turn off 1 set of lights (white)
• turn on 1 set of lights (red)
• turn on continuous rotation servo
• turn on traditional servo (starting @ 30-degrees , rotating 90-degrees , back)
• start play mp3 via adafruit mp3 shield

after few seconds should stop , return normal (white lights on, else off).

the shield appears functioning correctly , song plays , stops needed. red light , continuous rotation servo behave expected. trouble lies regular servo , white lights.

when button pushed, regular servo tries rotate beyond limit, , each time board reset, rotates appears 30 degrees. when mp3 shield not in loop, behaved expected (started @ 30-degree mark , rotated 90, etc).

the white lights begin flicker instead of turn off when button pushed. when mp3 shield isn't involved, turn off expected.

other deets:

• the lights connected via relay , have own external power supply. arduino turning relay switches on , off. white lights wired when no power supplied arduino relay, lights on. red set opposite.
• servo issues hitec hs-322hd deluxe

any can send way appreciated. i'm working on deadline, , can't seem fish out what's happening here.

here's code i'm working far:

    pinmode(whitelightpin, output);
    digitalwrite(redlightpin, high);  // set pin turn red lights off
    digitalwrite(whitelightpin, high);

    //set servos
    continuousservo.attach(13);
    regservo.attach(11);
    regservo.write(30);
    continuousservo.write(94);
   
  }
 
void loop() {
 
  buttonvalue = digitalread(a0);
 
  if (buttonvalue == high) {
   
    musicplayer.startplayingfile("1.mp3");
    delay(6050);
   
    digitalwrite(redlightpin, low);
    digitalwrite(whitelightpin, low);
    continuousservo.write(91);
    regservo.write(90);
    delay(10000);
   
    musicplayer.stopplaying();

    buttonvalue = 1 - buttonvalue;
    digitalwrite(redlightpin, high);
    digitalwrite(whitelightpin, high);
    continuousservo.write(94);
    regservo.write(30);
   
  }

}

hi , welcome.

post schematic please. hand drawn ok long neat enough read. details of power supply circuit. powering these leds , 2 servos 5v output of arduino example?
