Scripting in Adobe Forms - Hiding a field

Question

Hi Experts
I have some code that I just can't get to work - please advise where I am going wrong.
Looking at the folowing code segment (Javascript, at Client), I am running through a loop of items (PO Text Items). If I take the IF statement out around the statement where I hide the fields, it works well (in other words it hides every line), but I only want to hide lines where the item (ItemTextFromPO) is empty.
var oFields = xfa.resolveNodes("data.PO_Page.MainSubform.ItemSubForm.POItemText.DATA[*].ItemTextFromPO");
var nNodesLength = oFields.length;
for (var nNodeCount = 0; nNodeCount < nNodesLength; nNodeCount++)
     if ( xxxxxxxxxxxx.rawValue == "" )
          oFields.item(nNodeCount).presence = "hidden";
Please advise what I need to use in the IF statement to make it work?
Thanks

Hi Chintan
I know there is no index currently in the if statement - and that is my problem.
I am getting a table of texts for PO Items passed into a form. Some items may have more than one text item, and some may have none. For those with none, it will still have a dummy entry - i.e. a table entry with nothing next to it. A table might look like this:
0010     Text for item 10
0010     More text for item 10
0020
0030     Text for item 30.
So, Item 20 above has no text (an empty text line).
In the form, I have a repeating subform -  it repeats once for evry item. On this subform, I have an textfield called that can repeat many times, if necessary (like for Item 10 above in this example). In the context of the form, I have a where condition that linke the item texts to the items - in other words the texts appear with the correct items already.
However, I do not want anything to appear if the field is empty (like for line 20, in this example).
So, I have written the loop as you saw in my original question. This loop works - if I take the IF statement out, then it hides EVERY line. If I do not use a loop, it only hides the 1st line... so the loop is required.
I then need to 'ask' each item with the IF statement whether it is empty or not - and if it is, then hide it. So, I just need someone to tell me the correct syntax for the xxxxxxxxxxxxx in my IF statement. This should surely include the index (the counter of the loop) somehow, so that I can access each individual item.
I have tried many combinations, but none worked - so far.
Please let me know if I need to explain more.
Thanks,
Casper
