Thanks, Anthony.
1. I thought f.name gives the name as <table>.<field> but for the hidden
fields and form1.element, the field name alone is required. I will make a
note of it.
2. hidden is included to make sure that the update back end operation does
not make those fields as NULL. Not sure if the below alternatives will
work: (a) using 'readonly' attribute so that the values go to the back end
- but does it happen in all the browsers? (b) may be we can remove the
disabled attribute just before submitting the form?)
3. I missed explaining r. r is the record from the database containing the
values for all the selected record and I needed to set them as the values
of the hidden field. r has been fetched before the below code in the
function.
4. Simpler codes - noted and thanks a lot for the simplification.
