Hi
I design a HTML form and any entry have three part :
1 ) Display Label, It's a label for field.
2 ) Field Entry, It's a form object <INPUT> , <SELECT> <TEXTAREA> )
3 ) Error Msg, It's a anchor ( <A name="fieldname">).
I design a class for entry object .
Now i must check validation input data and if has error show a message in
Error Msg. For this work i must have a unique name for any entry.
With thanks for answer
