Conditionally assign a value to a parameter

Question

I'm using this code to conditionally assign a value to a parameter p_data_type:
<?if:H_ACCOUNT_HIER_DESC='EST'?><xsl:param name="p_data_type" select="'number'" xdofo:ctx="begin"/> <?end if?>
<?if:H_ACCOUNT_HIER_DESC='PAR'?><xsl:param name="p_data_type" select="'text'" xdofo:ctx="begin"/> <?end if?>
However, I'm getting the following error.
Caused by: oracle.xdo.parser.v2.XMLParseException: Duplicate variable 'p_data_type' definition.
Once I get this working, I want to use it as follows:
<?sort:current-group()/ACCOUNT_SEQ;'ascending';data-type='{$p_data_type}'?>
Does anyone have any suggestions on how I might do this?
Thank you,
Tam

Thanks, Vetsrini. Works great. I do have one further question if you don't mind. In the <xsl:when test...>condition below, why is the '//' reference required for H_ACCOUNT_HIER_DESC. The code didn't work unless I used the '//'
Here is my template code:
<?import:xdo://XXFIN.XXFIN_PSB_NUMBER_FORMAT.en.CA PROVINCE?>
<?start:body?>
<?for-each:XXFIN_PSB_GOS_EXP_ANNUAL_ACT_SUM?>
<?for-each:G_HEADER_PAGE?>
<xsl:variable name="p_data_type">
<xsl:choose>*<xsl:when test="//H_ACCOUNT_HIER_DESC='EST'">*<xsl:value-of select="'number'"/></xsl:when><xsl:otherwise><xsl:value-of select="'text'"/></xsl:otherwise></xsl:choose>
</xsl:variable>
Here is my XML:
<?xml version="1.0" encoding="UTF-8"?>
<XXFIN_PSB_GOS_EXP_ANNUAL_ACT_SUM>
<P_OUTPUT>E17-1</P_OUTPUT>
<P_ACCOUNT2_HIGH>
<G_HEADER_PAGE>
<H_RECIPIENT_NAME/>
<H_PROG_SUM_LEVEL>SV/SP</H_PROG_SUM_LEVEL>
<H_ACCOUNT_HIER>AC0000</H_ACCOUNT_HIER>
<H_ACCOUNT_HIER_DESC>EST</H_ACCOUNT_HIER_DESC>
Thanks again for your help.
