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.
