    Values "randomly" lost in a function passing

    Hello.

    I have these lines :

    function damages(i,fighter,damage2,damage3)
    {
    text.innerHTML += "<br>********** "+fighter[0][5]+ " : vie "+damage2[fighter[0][0]]+" -- fatigue "+damage3[fighter[0][0]];
    text.innerHTML += "<br>********** "+fighter[1][5]+ " : vie "+damage2[fighter[1][0]]+" -- fatigue "+damage3[fighter[1][0]];
    text.innerHTML += "<br>********** "+fighter[2][5]+ " : vie "+damage2[fighter[2][0]]+" -- fatigue "+damage3[fighter[2][0]];

    db.transaction(function (tx)
    {
    text.innerHTML += "<br>********** "+fighter[0][5]+ " : vie "+damage2[fighter[0][0]]+" -- fatigue "+damage3[fighter[0][0]];
    text.innerHTML += "<br>********** "+fighter[1][5]+ " : vie "+damage2[fighter[1][0]]+" -- fatigue "+damage3[fighter[1][0]];
    text.innerHTML += "<br>********** "+fighter[2][5]+ " : vie "+damage2[fighter[2][0]]+" -- fatigue "+damage3[fighter[2][0]];
    The two "text.innerHTML" bloc are the same.

    But the results are not the same :


    ********** Cat : vie 2 -- fatigue 3
    ********** Wolf : vie 3 -- fatigue 5
    ********** Rabbit : vie 0 -- fatigue 2
    ..

    ********** Cat : vie 2 -- fatigue 3
    ********** Wolf : vie 0 -- fatigue 0
    ********** Rabbit : vie 0 -- fatigue 0
    I mean... what ? Why some values are lost and not the others ?

    Okay. Then i've done some research, and added "(i,fighter,damage2,damage3)" to the internal function, like that :

    function damages(i,fighter,damage2,damage3)
    {
    text.innerHTML += "<br>********** "+fighter[0][5]+ " : vie "+damage2[fighter[0][0]]+" -- fatigue "+damage3[fighter[0][0]];
    text.innerHTML += "<br>********** "+fighter[1][5]+ " : vie "+damage2[fighter[1][0]]+" -- fatigue "+damage3[fighter[1][0]];
    text.innerHTML += "<br>********** "+fighter[2][5]+ " : vie "+damage2[fighter[2][0]]+" -- fatigue "+damage3[fighter[2][0]];

    db.transaction(function (tx)
    {
    text.innerHTML += "<br>********** "+fighter[0][5]+ " : vie "+damage2[fighter[0][0]]+" -- fatigue "+damage3[fighter[0][0]];
    text.innerHTML += "<br>********** "+fighter[1][5]+ " : vie "+damage2[fighter[1][0]]+" -- fatigue "+damage3[fighter[1][0]];
    text.innerHTML += "<br>********** "+fighter[2][5]+ " : vie "+damage2[fighter[2][0]]+" -- fatigue "+damage3[fighter[2][0]];

    })(i,fighter,damage2,damage3);
    };

    The funny thing is : Now, that work, BUT apparently it's the bad thing to do (the browser say i call as a function something that is NOT a function. Yes, but why it's work now, then ?).
