Can't make calcs with multiplication

[EchedelleLR]

Calculated field in with the error in XSL:

<td>
    <xsl:variable name="coste" select="unidades * precio" />
    <xsl:value-of select="$coste" /> €
</td>

Additional information:

• The issue is confirmed with last version of VSCode too. Not specific issue of VSCodium.
• If one tries an imported field like "precio" with a direct number in the XSL, there is no issue as confirmed by the person who tested it in VSCode.

Might be a bug in the XSLT parser itself. I'll be looping back around to a few of these issues soon.
