How to get specific page numbers to each template (per language and Per instance) when the template itself repeatable

So you want an individual page count for each english and spanish subform? 

Place a textfield “TemplateSpan” on each of the masterpages (Page1-Page2). Then add the following script into the calculate event of the subform “EnglishTemplate” and “SpanishTemplate”. It will populate the page counts to the field on the corresponding masterpages. 

// Individual page count for subform spanning multiple pages.
var nAbsPage = xfa.layout.absPage(this), // Absolute page num this subform begins (0-based)
	oPageArea = xfa.layout.pageContent(nAbsPage, "pageArea").item(0), // Reference to the master page used by the subform
	cPageName = oPageArea.name, // Name of the master page
	nSpan = xfa.layout.pageSpan(this), // Number of pages the subform spans
	nIndexStart = oPageArea.classIndex, // Index of first masterpage within span
	nIndexEnd = nIndexStart + nSpan, // Index of last masterpage within span
	// Resolve all master page instances that belong to this span
	oPageAreas = form1.resolveNodes('#pageSet.#pageArea.[$.name eq "' + cPageName + '" and $.classIndex ge ' + nIndexStart + ' and $.classIndex le ' + nIndexEnd + ']');

// Populate page details to textfield "TemplateSpan" on related masterpage
for (var i = 0; i < oPageAreas.length; i += 1) {
	var cTxt = "Page " + (1 + i) + " of " + nSpan;
	oPageAreas.item(i).TemplateSpan.rawValue = cTxt;
}
