First of all, this is not valid xslt stylesheet, because <xsl:stylesheet> can not contain literal result elements with null namespace, I'm about your <template> element. I suppose this is typo and you really mean <xsl:template>.
Second, you don't provide default value to abs param, so unless you provide actual value by processor-specific API, abs param will hold empty string (because <xsl:param name="abs"/> is filly equivalent to
<xsl:param name="abs" select="''"/>) and expression $abs * 3 will evaluate to NaN (Not A Number).
Try <xsl:param name="abs" select="5"/>, for example.

Well I need these vars several times in the stylesheet ... for colspan's, or when ... apply statements.

Excuse me for being so boring, but where is your real problem? :)
