Facing issue to Consume Variable value from Logic app to XSLT Mapping

Question

Currently, i am facing issue to set the dynamic value to XSLT map (which i am getting from Logic app.

In Logic APP transformXML action,i have passed XSLT parameter in the below format.

In XSLT i have declared my parameter and assigned the parameter value to inside <ns0 tag like below .

<xsl:param name="Custid"/>

<CustomerId><xsl:value-of select="$Custid"/> </CustomerId>

Expectation is what value i am passing from Logic app it should reflect in XSLTTransformXML file. But that is not working i am getting empty in the field like below.

Please suggest your valuable solutions.

Thanks
