How to link a value in a cell to a page number?

Question

I have a series of diagrams that I'd like to create a table for showing the page it's on, and a description of it. during creation, i an simply store the value of the page number in an array, and use it when creating the table, however, if the diagram is moved onto another page, then the cell shows the wrong page number, and the table loses meaning. Is there a way I can link the page number shown in the table cell with that of the page number it's currently on?

Excellent thank you. While I was creating this sample code, I kept seeing an undefined destination text with either PB or OV shown in the cross references. This was because the textframe inside the frame that contains the image wasn't set to the same geometricBoundaries as the container frame!
#target indesign
var doc = app.documents.add();
// add new page with image
var page = doc.pages.add();
var imageGraphic = page.place(File('image.jpg'));
var imageFrame = imageGraphic[0].parent;
imageFrame.geometricBounds = [0,0,100,100];
imageFrame.fit(FitOptions.fillProportionally);
// add text frame to imageframe for hyperlink dest
var tf = imageFrame.textFrames.add();
tf.contents = " ";    // insert blank text
tf.geometricBounds = [0,0,100,100];     // THIS IS VITAL otherwise the destination becomes invalid for some reason
var destination = tf.paragraphs.item(0);    // find text / char destination
var destination = doc.hyperlinkTextDestinations.add(destination, {name:"foo"});    // hyperlinktextdestination reference 
var creditPage = doc.pages.add();
var creditPageTF = creditPage.textFrames.add();
creditPageTF.geometricBounds = [0,300, 100, 400];
creditPageTF.contents = "...";
var xRefForm = doc.crossReferenceFormats.item("Page Number");   // Default CS5 xref format that shows "Page 45" etc
var sourceText = creditPageTF.paragraphs.item(0);
var source = doc.crossReferenceSources.add(sourceText, xRefForm);
var destination = doc.hyperlinkTextDestinations.item("foo");     // find text anchor by name from above
var myLink = doc.hyperlinks.add(source, destination);
myLink.visible = false;
very confusingly, there seems to be two types of cross references for cs5, cross references for text, which are actually hyperlinks, and crossreferences for tocs i believe (which I know nothing about atm!)
