yes thx, for your quick reply..

i already see the article and i still confuse about the loop condition of this codes..

i just want to add PlaySound Function when the loop conditions meet requirement to show the dot indicator.

In my reading : the loop start at line 58 (loop begin???) but for what requirement condition?
