• Hi Narasimha.

I am trying to figure out what your problems is. But i am having a hard time understanding what it is.

You ask for a "WantedTotal" and you show a "Current" value. You can then click on the sprite numbers to try and get the "wantedtotal".

That seems to work for you. So what is the problem you want to solve?

• hi cvp

my wanted total and sprite number is working fine.but my autual problem is the last sprite numbers are not having the proper wanted total and for me upto the last sprite number the Wnated total has to come like countable.

Ex:suppose if last sprite number having 9 the wanted total also has to be 9 , but for me it's coming like some other number. please share your ideas.

• ahh.. ok.

So the problem is that the wantedTotal asked for a number that is not possible to make?

• yes cvp

• Ok

I dont have time to make you an example right now. If you cant figure it out yourself I can make an example for your tonight.

But my approach would be:

Instead of creating the wantedTotal from a random number. Create the number from the numbers you have available on the sprites in the bottom. So pick 1,2 or 3(depending on how you want it) random numbers from the sprites in the bottom and them add them together to get a new wantedTotal

• thanks

Now i'll go with your idea .i'll try it now.if possible for you send the example. thanks

It might not be the most pretty example, but as far as i can tell it works <img src="smileys/smiley17.gif" border="0" align="middle">

• Thanks cvp

in your example , you have taken local variable v=2, can you explain me what does it mean.

• V is just a simple counter variable.

It is set to 2 as that is the number of sprites in the bottom it adds together to make the wantedTotal.

• thanks cvp
