I'm calling this function on multiple sprites after checking numberOfRunningActions()"to play same animation but it's not working only the first tagged sprite plays the animation. What am I doing wrong?

void    CGame::playAnimation(const char* filename, int tag, CCLayer* target)
{   
    CCAnimation*        animation    = CCAnimation::animation();
    CCSprite*           spriteSheet  = CCSprite::spriteWithFile(filename);

    for(int i = 0; i < spriteSheet->getTexture()->getPixelsWide()/SIZE; i++) // SIZE is an int value 
    { 
        animation->addFrameWithTexture(spriteSheet->getTexture(), CCRect(SIZE * i, 0, SIZE, SIZE));
    }

    CCActionInterval*   action =   CCAnimate::actionWithDuration(1, animation, true);
    CCRepeatForever*    repeatAction   =   CCRepeatForever::actionWithAction(action);

    target->getChildByTag(tag)->runAction(repeatAction);
}
