Variable indent based on xml data using xsl-fo start-indent

Question

I am trying to make a report of a peoplesoft tree which includes xml data to indicate the level of the tree.
I have a template which sort-of works but has some strange behavior. First I set a variable to the value of the treelevel, and multiply by ten to set the value for the indent that I want. I then apply that value for the indent to the start-indent attribute
<?xdoxslt:set_variable($_XDOCTX, 'x', (fld_TREE_LEVEL_NUM)*10)?>
<xsl:attribute name="start-indent" xdofo:ctx="table-cell"><?xdoxslt:get_variable($_XDOCTX, 'x')?></xsl:attribute>
These tags are put in a table row which repeats within a for-each group along with the data to get indented.
The problem is that the indenting seems to work but not consistently and some rows which clearly have different indent levels are printing as if they are at the same level.
Any ideas would be appreciated.

Hi! Use xsl:variable:
<xsl:variable name="var"><?fld_TREE_LEVEL_NUM*10?></xsl:variable>
<xsl:attribute name="start-indent" xdofo:ctx="table-cell"><xsl:value-of select="$var" /></xsl:attribute>
