Link rows and photos???

Question

Couple of tasks
Hello
I am using Indesign CS3 and I am trying to learn JS in order to complete some tasks.
I’ll put this in an example so as to make sence
I want to place 3 pictures with their labels (name of the jpg file). I know how to do that and how to format the labels in the style, color and size I need.
For example the texts in the labels are X1, X2, X3,.
I bring a table from an excel file with 3 rows and 2 columns.
-The text on the right column is the same with the text on the Labels (ex: row 1, column1: X1, row 2, column1: X2, row 3, column1: X3)
-The text on the left column is the description of X1-X2-X3 (for example, “row1, column1: X1 // row1, column2: pencil, B4 “)
I need
1. To say to indesign to find the same texts from the labels and the rows
(in the example : to find X1 in the labels and X1 in the rows.)
2:  To break apart , table’s rows
3. To replace each label with the corresponding rows
(in the example to replace label X1 with “row1, column1: X1 // row1, column2: pencil, B4 “)
Or perhaps, to place each row in the (example) top left of the corresponding picture.
There is a sample script in indesign that helps find the same objects but is it possible to specify it in particular texts or to specify it in texts (inside tables) and filenames??
Thank you in advance…

Answer 1

Thank you for your answer I think this might be extremely helpful
and if I have corectly understood you are probably right
I am really sorry about the terminology and the confusion
It’s a bit confusing for me as I have just started trying to understand scripts in indesign.
I named labels (as I have seen it before in another topic) the text that is placed on the images (name of the file , type etc…)
(for example it’s almost the same thing with Bridge tool: create indesign contact sheet , but I prefer to use a scipt in indesign as I have managed to manipulate, colour, type and size )
If the content of what I called “label” is called “caption paragraph” (or just paragraph???) then
I need to replace the contents of the first paragraph (the original "label") with the contents of the first cell of the row.
So I do the same with the rest of the paragraphs (labels)? I replace the second paragraph ith the contents of the first cell of the second row etc???
I am sure I’ll find this in the book about indesign script writing - but if there is no harm in asking - do I need to specify texts as caption paragraphs?
