hi, is there any document around which list procedures how to accomplish simple cgi tasks with dtml. say i get a input into a text box thru the browser with the name as valname. Then how do i print this valname thru dtml. ofcourse i checked out with the guides but could locate cgi calls, something called request i did find, but dont know how to use it. thankx ps: dont kick me out, everybody has to have a start.
