This is a big problem. But you can work around it by using specific
prefixes to your vars. Best is to avoid vars in your logicsheet. Use
one or two global vars as reference to some complex structures like
beans and set their properties. Once properties are set, call your
beans methods.

Try to nest <esql:param name="column"><xsp:expr>column_number</xsp:expr></esql:param>
elements in your <esql:get-string> tags. Should suffice.
Or, if column is determined statically be logicsheet, you need
<xsl:attribute name="column"><xsl:value-of select="$column"></xsl:attribute>
Mind you, perhaps you need to copy-of instead of value-of.
