Filemaker generated excel xml with xslt opens in excel mac 2011 but not in excel windows 2013
<p>I created an xml file with xslt transform from filemaker (on a mac).  File opens and formats as intended in Excel Mac 2011.</p>

<p>However when my client attempts to open the same file in Excel 2013 (on windows pc) , gets an error message that file can not be opened (they tried on 2 different laptops)</p>

<p>This is the log message created by Excel (Windows):</p>

<pre><code>XML ERROR in Table
REASON: Bad Value
GROUP:  Row
TAG:    Cell
ATTRIB: StyleID
VALUE:  GroupSubtotalCenter1

XML ERROR in Table
REASON: Bad Value
GROUP:  Row

ATTRIB: StyleID
VALUE:  GroupSubtotal1

XML ERROR in Table
REASON: Bad Value
GROUP:  Row
TAG:    Cell
ATTRIB: StyleID
VALUE:  GroupSubtotalPercent1
</code></pre>

<p>And here is a link to the file:
<a href="https://www.dropbox.com/s/inn6gs5pg7fnmqk/SalesReport.xls?dl=0" rel="nofollow">https://www.dropbox.com/s/inn6gs5pg7fnmqk/SalesReport.xls?dl=0</a></p>

<p>Note: I have been using the same styles on other reports generated by the same filemaker db, that open just fine both on Windows and Mac.</p>

<p>Any ideas why this is happening and/or how to fix/debug?</p>
