Dynamic watermark using - <xsl:variable name=”wMark” select=”xdoxslt:ifelse(SOB_NAME=”FOO”,”BAR”,’’)

Trying to create a dynamic watermark using -- <xsl:variable name=”wMark” select=”xdoxslt:ifelse(SOB_NAME=”FOO”,”BAR”,’’)”/>

 I'd like "wMark" to be populated with BAR when SOB_NAME comes back as FOO, and to be null when SOB does not come back as FOO.

I'm trying to get a watermark to show when the report is published from development, and not show when published from production.

I won't be using SOB_NAME in the end; I'm just trying to get the syntax for this function down.

I'm receiving this somewhat unhelpful error (at least for me, maybe I'm missing something):  Seems like I get this error whenever I have a problem with syntax.
