The reason your code isn’t running is because some code isn’t contained within a function, such as draw();
If you delete the last two lines:
```auto
println(input);
}
```
or move the _println()_ statement into draw then the code works fine

**Also** a lot of your visuals are still contained in the setup function, which will only draw once. I would move pretty much everything in _setup()_ to _draw()_ (_except_ the _size()_, _textSize()_ and _frameRate()_ function)

I know but divided button is not work i tried for example 9/3 it show infinity answer of this problem

It looks like there’s no code that is setting input2 equal to any number, so the denominator will always be zero (hence infinity)

Oh ok. Well I was wrong about the input2 thing because I noticed you actually do have code for this. I would print input2 after parsing the ordinary input text and test different numbers. If the result is always 0 then it may be a problem with parsing
```auto
println("=");
input2 = parseInt(input.substring(1)); //.substring(1) removes 1 symbol from the text
println(input2);
input = input + "=";
```
If this is the case then try adding a _radix_ to your parseInt()
input2 = parseInt(input.substring(1), **10** ); //.substring(1) removes 1 symbol from the text

Oh. It’s actually a problem I’ve introduced into their code by helping them in another thread by adding `.substring(1)` to the code above, so that input2 can be `+3` or `-3` or `x3` or `/3` and each would be parsed as `3`, yet I didn’t notice that they don’t actually add the `/` symbol, so it gets sent as `3`, goes through `.substring(1)` that removes the first and only character, turns into nothingness, which is then parsed as 0.
Solution?
Make your code for `/` (divide) set `input` as `/`, exactly the same way other `+ - x` functions do it.
Try figuring that out yourself! You gotta start somewhere doing that and not have other people write it for you, isn’t that right? 😃
