Hi,

I have created 3 properties in a document.

1. MediaPicker
2. Left (numeric)
3. Right (numeric)

The user selected an image for the page then has two numeric fields to put in a top and left value which I will set as css properties on the image.

Two questions:

1. Is there anyway I can stop the user typing in text? If they do, and save the document then the field ends up being black.

2. If they do type in a text value or leave it blank, my XSLT checks do not reflect the fact that nothing is in there,

An example of my XSLT is below: No matter what I do I cannot seem to get a check back on the empty property passed into the macro.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
    version="1.0"

<xsl:template match="/">

<!-- start writing XSLT -->
  <xsl:choose>
    <xsl:when test="$ImgTop='NaN' or $ImgTop='' or $ImgTop=Null">
      Hey nothing came through.
    </xsl:when>
</xsl:choose>


</xsl:template>
