... was not declared in this scope

I dont know why am getting this message because i am quite sure that there was no problem in the past.
In fact, i have uploaded this code to 10 arduino's before i got this message.
IDE 1.6.5 --> linux ubuntu.

#include "U8glib.h"
#include <EEPROM.h>
#include <Keypad.h>

volatile byte coinPulseCount = 0;
volatile unsigned long pulseTime;
byte newCoinInserted;
byte coinValue = 0;
#define pulseThreshold 450

// ---- PINS
#define relay 7
#define coinChanger 4

// ----- coin variables
float coin1 = 0.10;
float coin2 = 0.20;
float coin3 = 0.50;

....

float f = 0.00f; //Variable to store data read from EEPROM.
int eeAddress = 0; //EEPROM address to start reading from

// --- array for codes
#define Password_Lenght 5
#define Time_Lenght 15
char Input[Password_Lenght];
String InputTime;

char SetTimeKod[Password_Lenght] = "1234";
.....

I get error Password_Lenght was not declared in this scope but highlighted part is
the #define pulseThreshold 450...

Any ideas ?
A.

Replace this...

#define Password_Lenght 5

...with this...

const int Password_Lenght = 5;

If that does not help, this surely will...

most of the code is compiled until :

if (data_count == Password_Lenght - 1)

Then i get the same error....

Btw. i have few others #defines in the same code part but they are working OK.

A.

If you REALLY want help, you will:
Post ALL of your code.
Post the EXACT, COMPLETE error message.

... will NOT compile for anyone.
