Conditions --- IF - ELSE IF

Help me - I created an object where the girl in the photo and asks for the correct track number. When we entered the correct number, it keeps going until the next issue.

I wonder, how could it do, if dragged the incorrect number, activates an audio Incorrect or try again.

I am using the code below but I can not imagine how to do this if - else if, as I am now starting to edge and jquery.

Thank you very much.

// make an array of the draggable symbol names

draggableEl = ['_13','_17','_21','_26','_31','_35'];

// make an array of the droppable element names

droppableEl = ['_13target','box17','box21','box26','box31','box35'];

// have only the first element be draggable

// set up the droppable to accept each draggables

for (i=0;i<droppableEl.length;i++){

  sym.$(draggableEl[i]).addClass('C'+i);

  sym.$('.C'+i).draggable({

  revert: 'invalid'

});

  sym.$(droppableEl[i]).droppable({

  accept:'.C'+i,   // use class for accept

  drop: handleDropEvent

  });

}

k=0;

function handleDropEvent(event, ui){

    ui.draggable.draggable( 'disable' );

    $(this).droppable( 'disable' );

    // place draggable where needed. could be left, top

   // ui.draggable.position( { of: $(this), my: 'left', at: 'top' } );

    ui.draggable.position( { of: $(this), my: 'center', at: 'center' } );

    ui.draggable.draggable( 'option', 'revert', false );

    k++;

    if (k==1){

    sym.getSymbol('correct').play();

    // play animation here.

    }

}
