Crgbarray not meshing with crgb in declarations

Hey there everybody. I'm trying to combine some codes and I'm having a bit of trouble. I already the "Cylon" FastLED code in part of my sketch, and I'm trying to merge to "TwinkleFox" FastLED code with it (among a few others), and I'm running into an issue. I thought that I had everything correct in my declarations, but when I go to verify my code, I get an error effectively stating that in my definitions the amount of LEDs is already assigned to a definition and that CRGBArray does not work since I already have a number value assigned to NUM_LEDS....

#include <Adafruit_NeoPixel.h>

#include <FastLED.h>
#define LED_TYPE WS2811
#define COLOR_ORDER GRB
#define LED_PIN 6
#define DATA_PIN 6
#define VOLTS 12
#define MAX_MA 4000
#define LED_COUNT 100

#define NUM_LEDS 100

CRGB leds[NUM_LEDS];
CRGB gBackgroundColor = CRGB::Black;
Adafruit_NeoPixel strip(LED_COUNT, LED_PIN);

CRGBArray<NUM_LEDS> leds;
#define TWINKLE_SPEED 6
#define TWINKLE_DENSITY 2
#define SECONDS_PER_PALETTE 5
#define AUTO_SELECT_BACKGROUND_COLOR 0
#define COOL_LIKE_INCANDESCENT 1
CRGBPalette16 gCurrentPalette;
CRGBPalette16 gTargetPalette;

This is what my definition section looks like, and if anybody could give me some input on what I can do to get these codes to merge, it would be hugely appreciated! Thank you!

Read the forum guidelines to see how to properly post code.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

Is that the problem?

Why two different names for 100?b

Please remember to use code tags when posting code.

Hey sorry for the formatting issues.... Here is my whole code and my error message:

I'm extremely new to working with Arduino, and have no previous coding experience, so this has been like going through the ringer hahaha. I have 2 different names for the 100 because when I remove the CRGBArray, it tells me I have an invalid initialization of reference.... I'm not sure why one set of code calls on the CRGBArray, and one will simply except the other version...

Post code in code tags.

You can't have two separate variables named "leds". You will have to rename one of the two. The sketch that was using the variable you rename will have to use the new name.

You've still got two entities called "leds"

So I edited the code to not include both leds, which says that my code is accurate, but now when I actually upload them to my lights, the final twinkle sequence won't run, even though when I verify my code everything says it's correct. Unsure why it is excluding just one of my sequences....

Is that the sequence that used the 'leds' that you deleted or renamed?

No all sketches that compile without errors will do what you want them to. They can only do what you tell them to.

I had simply removed the section of code #define NUM_LED and left the one labeled LEDarray. I also tried to pull some simple adafruit code into the sketch that I am trying to compile with my larger sketch, and I was having similar issues where the adafruit pattern I added nullified the twinkle pattern that I added it to. No alterations to the original code, just tried to add the necessary code to have a second flashing pattern accompany the twinkle.

Thank you guys for all your help!
