Respected sir,
I am working in Health Department. I am maintaining my Record . I want to auto up to date the given value.

example --
field1=St date
field2=1st follow up
field3=2nd follow up
filed4=end follow up

1st follow up = St date+2months
2nd follow up= St date +4months
end follow up= St date+6 months.....
When I will put my St date in filed1.I need automatically replace the value according to the given condition.

First output the data from the database and keep track of the primary key.eg if field 1 is output ,provide a link and embed the key in it like www.field 1.php?id=the I'd of the record from database.

So wen you click the link, on the page were it takes you provide a get variable which wil pick the key from the url. Compare it to the one in the database and update accordingly..
