RE: [xsl] Can not convert number to a NodeList

["Carlos M. S. Bento Nogueira" <cmsbn@xxxxxxxxxxxxxxxxx>]

Aron, 
the reason why this code you suggest doesn't work is that my inputs are declared as
<input type="radio" id="{generate-id()}" name="{$id}" value="{@value}">
and the generate-id() functions probably loses reference to the context node when used inside 
the <xsl:template match="opt">(now fi:item) as you suggested.

I adapted your snippets to produce this:
<xsl:for-each select="fi:selection-list/fi:item[position() &lt;= current()/$line]">
<xsl:variable name="r" select="position() - 1"/>
	<tr>
                   <xsl:apply-templates select="fi:item[position() &gt;= $r * $column + 1
                   and position() &lt;= $r * $column + $column ]"/>
	</tr>
</xsl:for-each>
(...)

<xsl:template match="fi:item">
	<td>
	<input type="radio" id="{generate-id()}" name="{$id}" value="{@value}">
	(...)
</xsl:template>

Also the output i'm trying to achieve is e.g. for a table with 2 lines and 
2 columns is

<td>
	<input>
</td>
<td>
	<input>
</td>
<tr>	<!--I can only have (($number_of_lines) - 1) tr tags -->
<td>
	<input>
</td>
<td>
	<input>
</td>
</tr>

TIA and TG(Thanks again),
CarlosN.
