I am designing code to control 2 light strips(cold white and warm white) with pushbuttons and an LCD (Using PT6961, link to the library can be found [here](https://web.archive.org/web/20161127234429/http://gtbtech.com:80/?p=528)). When adding the debouncing code to it everything broke...As always(at least for me) the help dialog is useless.  
Here is my code:

The error message:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

```

I know it is really simple to debug this, but I'm unable to...

Please post your code on this web site, not expect us to follow a link to somewhere else. Note it is essential to post YOUR code exactly as it is in the IDE when it produces errors.

I notice that you have other errors, specifically regarding the use of {}

Thanks.

You need to end loop() with a suitably placed } BEFORE you start defining the other functions.

Oh...I see now, I looked at code and it must be I removed it it accidentally. Works like a champ. Thank you!!!

The key errors are these two:

```cpp
led_controller:194:32: error: a function-definition is not allowed here before '{' token
 void cold_white_pwm_increase() {
                                ^
led_controller:339:1: error: expected '}' at end of input
 }
 ^

```

The second one means there is a '}' missing somewhere. The first one usually means that you are missing a '}' (or have an extra '{') in the previous function declaration.
