[htmltmpl] Help: HTML::Template Problem

[Chan W. T. <cs...@st...>]

Hi Philip,

Thank you very much for help. Your explaination is very clear. Since I am used to program in C++, I am quite confused about the usage of perl's variables and objects, especially their declaration and convention. Would you give me some advice, please?

Also, I heard that using HTML::Template we could define a variable and a counter in the template. Could you tell me how to use such features, please? I am using HTML::Template version 2.5 . Thanks a lot.

Yours,
cwt
