When Magento is trying to look to Mage_Somemodule_ instead of your own module, it does means that it did not found your own file or your own module.

Three possible reasons :

  1. Your module is not recognized at all, maybe something is wrong in your module definition
  2. Something is wrong/mistyped in your config.xml
  3. Something is wrong/mistyped in your class name

Be sure you have everything right from the tutorial and/or copy paste your code here so we can help further

In this case the two xml are wrong in the way that it should not ignore case sensitivity

CeckosLab_SmartView.xml

<?xml version="1.0"?>
<config>
    <modules>
        <CeckosLab_SmartView>
            <active>true</active>
            <codePool>local</codePool>
        </CeckosLab_SmartView >
    </modules>
</config>

config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <CeckosLab_SmartView>
            <version>1.0.0</version>
        </CeckosLab_SmartView>
    </modules>
    <global>
        <helpers>
            <smartview>
                <class>CeckosLab_SmartView_Helper</class>
            </smartview>
        </helpers>
    </global>
</config>

If your helper error contains Mage_ before your module, it means your helper is either not defined or defined incorrectly in your module's xml or you are calling it incorrectly.

If it is defined correctly this should work:

Mage::helper('smartview')->doSomething();

or try:

Mage::helper('ceckoslab_smartview')->doSomething();

Also, make sure you clear the cache as xml is cached heavily.

Hope this helps

Make enrty in config.xml

<global>
......
<helpers>
    <test>
        <class>Module_Test_Helper</class>
    </test>
</helpers>
......
</global>

Create a Data.php file inside Helper folder and write following code

<?php
class Module_Test_Helper_Data extends Mage_Core_Helper_Abstract
{
}

Thats it you need to do now if you call this code it will not throw any error:

<?php Mage::helper("test")->actionname(); ?>
