I don't know why, but I'm getting:

On the last part here, it is not working. It gives error code 1005
The alter table at the bottom is the probably the issue. I am just not sure how to fix it. Any help is appreciated. Thanks.
The foreign key is incorrectly formed.
You connect customer.c_ID should be equal to relationaltable.c_order
customer.c_ID is varchar(15) NOT NULL
relationaltable.c_order is int(100) NOT NULL
The data type and also the length has to be matching
I'm creating a database of greatest Movies, and i'm getting error:
ERROR 1005 (HY000) at line 19: Can't create table 'Greatest_Movies.genre' (errno: 150)
I have checked this Post:
Error Code: 1005. Can't create table '...' (errno: 150) and tried lot of things but with no succes.
This is what actually have:
DROP DATABASE `Greatest_Movies`;
CREATE DATABASE `Greatest_Movies`;
USE `Greatest_Movies` ;

`id` INT UNSIGNED NOT NULL AUTO_INCREMENT,
`film` VARCHAR(255) NOT NULL,

What i'm missing?

This script work and tested, try it:

I think you need to remove the comma from the end of this line:
`genre` TINYINT UNSIGNED NOT NULL,
And also after:
`name` VARCHAR(255) NOT NULL,
As #Solarflare said on the comments, I did this changes:

I am trying to create database table and get them connected by mysql FOREIGN KEYS. I have ensured that my data types are identical. I also ensure that my tables are made before added the FK. Any advice would be greatly appreciated.

The last table n creation, shows an error as
"Error Code : 1005. Can't create table 'sa38team4.transout'(errno: 121)"
Could anyone please help me?
Check out this post : MySQL errorno 121
As said :
Check that all your constraints are really spelled out correctly, also check that there's not any other tables that uses the constraint names ItemID or EmpID
So I think that you may use another name into your TransOut table for ItemID & EmpID
I have tried everything in solving this issue and yes I know that this type of question is already asked here but I could not solve my issue
It is mysql database
Error Code: 1005
Can't create table '.\project\comments.frm' (errno: 150)
the foreign keys are matching in structure (i.e length and type) then what can be the possible problem in the table creation
Table which is giving error is comments:

`description` VARCHAR(100) NOT NULL,
`user_id` INT(10) UNSIGNED NOT NULL,

FOREIGN KEY (`post_id`) REFERENCES `posts`.`id`,
FOREIGN KEY (`user_id`) REFERENCES `users`.`id`,
PRIMARY KEY (`id`)
) ENGINE=INNODB DEFAULT CHARSET=latin1;`
Here is posts table which is already created in the databas
CREATE TABLE `posts` (
`id` int(10) unsigned NOT NULL auto_increment,
`title` varchar(30) default NULL,
`description` longtext,
`image` varchar(50) default NULL,

Here is the users table which is also already created in the database

Your syntax is incorrect. The REFERENCES keyword should be followed by table (columns):
CREATE TABLE `comments`(
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`description` VARCHAR(100) NOT NULL,
`user_id` INT(10) UNSIGNED NOT NULL,
`post_id` INT(10) UNSIGNED NOT NULL,
FOREIGN KEY (`post_id`) REFERENCES `posts` (`id`),
FOREIGN KEY (`user_id`) REFERENCES `users` (`id`),
PRIMARY KEY (`id`)
