Something like (defun add-artist () (with-output-to-string (*default-template-output*) (fill-and-print-template template/printer values))) should do it. Note that FILL-AND-PRINT-TEMPLATE prints its output to the stream *DEFAULT-TEMPLATE-OUTPUT* and TBNL wants a string returned by the handler, so the code above makes sure everything printed to this stream ends up in a string which is returned by the function. This assumes that ADD-ARTIST is a handler, not a dispatcher. > Also another issue I am having is get-parameters, get-parameter, > post-parameters and post-parameter all don't seem to work.

WITH-HTML is the macro which uses CL-WHO from the test suite, right? If that's the case you must wrap the form (GET-PARAMETERS) with something that asks CL-WHO to include it in the output, otherwise it'll only be evaluated for its side effects. One of (str (get-parameters)) (esc (get-parameters)) (fmt "~S" (get-parameters)) should do it. Does that help? Cheers, Edi. --===============8284419552150183063==--
