Issue in using custom settings option values in add_action init hook

I have added custom setting options page under WordPress settings and those are working perfectly. I have tested their values also. But when I am using those values inside function file within add_action init hook to perform something on form submission, those values are returning as null. Everything is working except those values return as null. A few examples will really help me! Thanks in advance ??

`add_action(‘init’, ‘myFunc’);
function myFunc(){
$myoptions = get_option( ‘custom_option’ );
$trueorfalse = $myoptions[‘my_swicth’];
$alertemail = $myoptions[‘alert_email’]; // both working outside
if( 1 == $trueorfalse && ‘[email protected]’ == $alertemail ){
//do something
}
}`
