Javascript For loop not working within a function

Question

Hi all,
I'm a beginner to LiveCycle and I cant seem to get a loop working within a function.  The function is being called successfully because when I manually create the code it works but I am trying to clean things up.
So here is my working example:
function hideContent() {
        MainFlowedSub.LevelsSub.Table1.presence = "hidden";
        MainFlowedSub.LevelsSub.Table2.presence = "hidden";
       ... and so on....
         MainFlowedSub.LevelsSub.Table8.Row1.presence = "hidden";
        MainFlowedSub.LevelsSub.Table8.Row2.presence = "hidden";
       ... and so on....
However when I try and creat a loop instead of listing every sing table/row nothing happens. this is important to my project as there will be alot of different rows depending on radio button selections earlier in the form.  Below is the current state of my code:
function hideContent() {
    var i=0;
     for (i=1;i<=5;i++)
         MainFlowedSub.LevelsSub.Table[i].presence = "hidden";
    var j=0;
     for (j=1;j<=23;j++)
         MainFlowedSub.LevelsSub.Table8.Row[j].presence = "hidden";
    var k=0;
     for (k=24;k<=88;k++)
         MainFlowedSub.LevelsSub.Table8.Row[k].presence = "hidden";
this will then continue as there will be hundreds of rows.
Any help will be greatly appreciated and I am sure I am making a basic error  so thanks in advance.

thanks for your help paul.  Again, really appreciated as I know very little about all this.
Unfortunately its still not working... One thing I am sure of is that I am doing something very basic wrong. So here is my code, I have applied your suggestion above which will cover all my data:
To give an understanding, I have 5 tables of content, each has i amount of rows. and I am running this script to clear/remove all items being displayed.
function hideContent() {
    for (var i=1;i<=5;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table[" + i + "]").presence = "hidden";
    for (var i=1;i<=71;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table8.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=93;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table9.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=99;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table10.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=101;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table11.Row[" + i + "]").presence = "hidden";
    for (var i=1;i<=87;i++)
        xfa.resolveNode("MainFlowedSub.LevelsSub.Table12.Row[" + i + "]").presence = "hidden";
It has to be something to do with my For loops because if I manually insert each line it works perfectly.
Thanks again,
johnny
