Errror::Illegal number of arguments or types of arguments in XSLT

Question

HI All,
In our scenario we are using XSLT mapping with java enhancement.Its working fine in Stylus studio but when the same is imported into XI its throwing the below mentioned error:
                 javax.xml.transform.TransformerException: com.sap.engine.lib.xml.util.NestedException: Illegal number of arguments or types of arguments in a call of function 'Trans:Convert'.
Our requirement is that we are summing up the Field "Grant_Amount" which occurs multiple times in the source structure.PFB the XSL and the source XML:
<
XSL:
===
<Sum>
      <xsl:value-of select="Trans:Convert(//Grant_Amount)"/>
</Sum>
XML:
===
<Recordset>
      <DETAILRECORD>
         <Grant_Amount>$100.00</Grant_Amount>
      </DETAILRECORD>
      <DETAILRECORD>
         <Grant_Amount>$200.00</Grant_Amount>
      </DETAILRECORD>
</Recordset>
Java Code:
========
package com.company.group;
  public class String2Number
      public static String Convert(String[] a)
                      double sum=0;
                      String[] temp = new String[100];
                     for(int i=0;i<a.length;i++)
                              temp<i> = (a<i>).replaceAll("[,
$
                                     sum=sum+Double.parseDouble(temp<i>);
                        return sum+"";
>
Please guide me into the right solution.
Thanks and Regards,
