I hope you don't mind if I make a suggestion, Lisheen. The best way to thank people who have helped you is to post your thanks in the thread you started...in other words, provide an 'answer' yourself. The people who offer answers usually return to see if anyone else has added anything, so they will see your thanks then.
If you offer individual thanks to all the people who have helped, you take up space on the page and that pushes other people's questions down and then onto Page 2, where they may never be seen. Thanks.
