Expression Need to help with one calculation

I have 3 global variables:

Acurrent

Bincome

Cmax

Global variable "Acurrent" have 300

Global variable "Cmax" have 500

Global variable "Bincome" will be have random number lets for example set to 400

now when i click button

system should fill "Cmax" to his maximum variable (500)

Add "Bincome" (400) to "Acurrent"(300)

BUT when "Acurrent" is 300 we can add only 200 from "Bincome"

so finally after clicking button

we should have calculation

A-500

C-500

B-200

SECOND EXAMPLE

when Cmax have only 50

and Acurrent have 0

We take from Bincome only 50

IGDev

Add another variable to as a placeholder for the income to add, then do:

Set tempToAdd to Acurrent + Bincome > Cmax ? Cmax - Acurrent : Bincome

Set Acurrent to Acurrent + tempToAdd

Set Bincome to Bincome - tempToAdd

(Cmax - Acurrent) = MaxFill

If Bincome > MaxFill

. .... then NewAcurrent = Acurrent - MaxFill

& NewBincome = Bincome - MaxFill

If Bincome <= MaxFill

. ... then NewAcurrent = Acurrent - Bincome & NewBincome = zero

Or getting MaxFill out there again (it explained well with)

If Bincome > (Cmax - Acurrent)

. .... then NewAcurrent = Acurrent - (Cmax - Acurrent)

& NewBincome = Bincome - (Cmax - Acurrent)

If Bincome <= (Cmax - Acurrent)

. ... then NewAcurrent = Acurrent - Bincome

& NewBincome = zero

Under the assumption that Bincome cant be negative.

No, that is wrong, i suppose Acurrent cant be less than zero too.

im so confused about this

can you show this in capx?

If all you care for is capping your Acurrent variable just go:

Set Acurrent to

Bincome+Acurrent>Cmax?Cmax:Bincome+Acurrent

If you really need Bincome changed upen exceeding that threshold

set Bincome to

Bincome+Acurrent>Cmax?Cmax-Acurrent:Bincome+Acurrent

Then you can add Acurrent and Bincome

Haha, you quoted me, now i cant erase my stupid comments. Here goes :

Legal maximum for Acurrent = Cmax

Possible illegal maximum >> Bincome + Acurrent = bigger then Cmax

Everything bigger then Cmax goes back to Bincome

So .....

Local variable temp

temp = min(Bincome + Acurrent,Cmax)

Bincome = (Bincome + Acurrent) - temp

Acurrent = temp

i see now what is missing

when i calculate first time

From B 200 goes to A abd 200 stay

its possible to make this without Textboxes?

For example when my A is equal to C

A should be changed to 0

and i we should have posibility to click again and add rest from B to A variable?
