After creating a ZSearch interface for two ZSQL methods, I've realized that the input form created by ZSearch contains something like follows: [we are within a form...] <tr><th><built-in function id>/first name</th> <td><input name="<built-in function id>/first_name" width=30 value=""></td></tr> <tr><th><built-in function id>/last name</th> <td><input name="<built-in function id>/last_name" width=30 value=""></td></tr> I am very curious what effect the <built in function id> tag has. I guess, it is substituted by the id of the ZSQL method the form is currently querying (keep in mind that the ZSearch made this one form for two ZSQL methods). However I am not sure that my tips are good, if anyone has ever worked with <built-in> tag, please tell me/us how to handle it. Thx in advance, e-M
