I think you have to first check that in extension helper file exist or not.

Go to ExtensionsMall/SizeChart/Helper/Data.php where class ExtensionsMall_SizeChart_Helper_Data extends Mage_Core_Helper_Abstract should be exist.

Also check in ExtensionsMall/SizeChart/etc/config.xml file that helper is defined or not as below:

<helpers>
    <sizechart>
        <class>ExtensionsMall/SizeChart/Helper</class>
    </sizechart>
</helpers>
