Hi everybody, I was second time to sent this letter to you because you didn't reply my letter that i sent it in two days before. I have the tree like: +index_html(DTML Decoment) -lib(folder) -lib1(subfolder) +introducation(DTML Document) +history(DTML Document) : -lib2(subfolder) +introducation(DTML Document) +history(DTML Document) : -lib3(subfolder) +introducation(DTML Document) +history(DTML Document) : In the index_html has some lines: <!--#var introducation--> <!--#var history--> : If i call http://../../lib/lib1/index_html , it will return the introducation and history of lib1,etc. I want to use "in" tag instead of above lines that were inside the index_html and change the id of DTML Document(0001,0002,...) in the subfolder of lib, so that i can just change the id(0001,0002,...) or add a id(eg. 0004) to change my web page. I don't need to change anything in the index_html later. How can i do that? Hope that you can reply my letter as soon as you can! Thank you very much. Elaine Kong.
