Hi Gang Wu,

This is really a question for the webmacro-user list. This is the list for 
people who are activel working on the WebMacro code (developers).

I'm afraid it's not that simple. In this kind of scenario you need to 
generate unique field names based on your data / field number i.e. <input 
name="field3_submit">.

Then your servlet parses all the request parameters to see which one has a 
value.

That's one way of doing it anyway.

Best wishes,
