Thanks for the response Kyatric but the stars are not showing properly. I even added something to work for the arrows. May be I am doing something wrong.
For the Question 1: What Wisdoms posted second time was fine BUT a small bug. If I finish my level 1 with one stars, Total stars collected says 1 stars. Again if i play the "level 1" and finishes with 3 stars, It should shows as 3 stars, but it is adding with that previous 1 star and says 4 stars.
For the question 2: I even added 3 new sprites, arrow 1,2,3 in your file. And given cmd says, if I click the arrow 1,set value arrow =1.but the stars are not changing. Just showing one arrow always.
