Re: How can I chang the value og a global variable?

Hello everybody,

 I'm working with jstl. I've a jsp that has the structure of a xml. I need to
make a table with paging. I obtain the values of the table with jsp tags, and
mount the xml. To make the paging a need to know what is the last id of the table:

      <entrys>
              <entry><s2k:GetData dataName="{$tabla}" columnNum="1" /></entry>
              <entry><s2k:GetData dataName="{$tabla}" columnNum="2" /></entry>
              <param><s2k:GetRowNumber tableName="{$tabla}"/></param>
      </entrys>  

 Is to say, in the node param I have the value of this ID. In the xsl I need to
take only the last index, because this is the correct.

 When I had the correct value of this variable I need to introduce a script code
to finish.

 A lot of thanks,
