7 – Error: Call to undefined function in inc file


I searched for an explanation to this issue but didn’t find anything. I have other sites where this is working but not in this one.

So, my module info file (draws.module):

name = draws
description = Draws custom module
package = Draws Modules
core = 7.x

files() = draws.fixturesSavings.inc

In my draws.module I have this function (lines 289 to 231):

function saveToDatabase($response) {
    fixtures_saveToDatabase($response);
}

And then in the same folder of my draws.module I have the inc file (draws.fixturesSaving.inc):

<?php
function fixtures_saveToDatabase($response) {

And when I call function saveToDatabase, I get the following error:

Error: Call to undefined function fixtures_saveToDatabase() in saveToDatabase() (line 290 of /home/.../sites/all/modules/custom/draws/draws.module).

What am I doing wrong here?

Thank you.
