Unable to pass or get a parameter value on to Bi Publisher sub-template

I have used the following script to pass a value from main template to sub-template, but i am not able to get (transfer to) the value on to the sub-template.

XML Data:

<?xml version = '1.0' encoding = 'utf-8'?>

<!--Generated by Oracle BI Publisher -Dataengine, datamodel:_Custom_Human_Capital_Management_Test_HR_Report_DM_xdm -->

<DATA_DS>

<G_1>

<FULL_NAME>Mr. X</FULL_NAME>

</G_1>

</DATA_DS>

Sample Main Template:

<?import:xdoxsl:///Custom/Human Capital Management/XX_TESTSUBTEMP.xsb?>

<?call@inlines:TESTSUBTEMP?>

<?with-param:pName;./FULL_NAME?>

<?end call?>

Sample Sub Template:

<?template:TESTSUBTEMP?>

<?param:pName;string(‘Unknown’)?>

<?pName?>

Test template
