Add value of all objects?

Hi, how would I go about adding Value A of each instance of Object A?

i.e. I have 2 object a's, 1 with value a of 20 and the other of 10, how would I add this up to get 30?

No worries i made an example.

It uses a loop with a condition "Pick highest Private Value" and then adds to global value, change private to 0 and then again until every private is 0.

Or you could just use

+ For each Sprite

-> Add Sprite('Variable A') to global variable 'count'

Awesome! Thanks for the help.

Or you could just use

+ For each Sprite

-> Add Sprite('Variable A') to global variable 'count'

Sorry, but if I do that it just keeps adding to the total, rather than just show the total. Unless, I did it wrong.

do you mean the event is running more than once? - either add trigger once or add always-> set count to 0 above it if you need it to always evaluate it

Yeah, I tried that but it's acting all funky. I'll post my cap in the upload so maybe someone can look at it.

It's up. (Custom Slider Bar not working)
