SPROXY error testing outbound proxy interface

Hi,

I am trying to test an outbound proxy interface using SPROXY but am getting the following error:

Apart from the above messages there is no more help available. When I try testing the generated XSLT program using SXSLT_TEST it gives an error "No valid XSLT program supplied". I have checked and the auto generated XSLT program does exist.

Any help appreciated.

Thanks

Che
