javax.xml.transform.TransformerException

Hello

I am having XSLT to transform from my source format to target format. I tested the XSLT with the source XML file using XSLT Tester utility of SAP-GUI and it runs fine.

But when it is imported it gives the error

************************Start Message****************

javax.xml.transform.TransformerException: com.sap.engine.lib.xml.util.NestedException: Variable '$t_status' has not been bound to a value

************************End Message*****************

the variable t_status gets the value conditionally and hence sometimes it may be empty.

Does anyone know how to define a variable in XSLT without binding a value to that?

Thanks in advance.

Regards
