hi to all. i have two radio buttons with one name. and also have one text area box. Depending on first radio button is chosen It will allow 2 entries(Enter key words Separate by comers) per line, and at the same second radio button chosen it will allow 4 entries(Enter key words Separate by comers per line). how to do. give an idea.

Here's a good example in a forum (you'll need to scroll to the bottom - it's a long thread!): http://www.codingforums.com/archive/...p/t-71233.html

k. that code is working fine. but in that text area each line may or maynot have 2comers(,) but not have more than two comers(,). how to do?

i mean each line have 3 keywords. no need to count letters per line. but each keyword separated by commas. forexample: abc is one keyword. so we are entering like this " abc,abc,abc". there is no need to count no.of characters per line. and also textarea allow to maximum four lines and each line have 3 keywords. i tried a lot....but i didnt found solution for this.

my requirement is
textarea have 3 keywords. no need to count letters per line. but each keyword separated by commas. forexample: abc is one keyword, defgh is another keyword, kalpana is another keyword. so we are entering like this " abc,defgh,kalpana". there is no need to count no.of characters per line. why b'coz we dont have length of the keywords. each textarea must contain 3keywords seperated by commas. for this 3 keywords sepparated by only 2 commas. so we count only commas. i think u understood.
