UNDEFINED OFFSET MESSAGE WHEN USING USER CREATED ARRAY AT RUN TIME

[rogerad]

SEE PREVOUS POST

I CAN ADD THE ITEMS INTO THE ARRAY CORRECTLY NOW BUT WHEN THERE ARE MORE THAN 10 ITEMS , THE 10 TH ITEM AND LATER IS AN UNDEFINED OFFSET MESSAGE
EG ERROR MESSAGE ON THESE LINES

'10' => $option_wp_roles_string[10],
'11' => $option_wp_roles_string[11],
'12' => $option_wp_roles_string[12],
'13' => $option_wp_roles_string[13],

THE MESSAGE DOES NOT APPEAR ON ALL MY COMPUTERS ONLY ON 1 OF THEM

Notice: Undefined offset: 12 in C:\xampp\apps\wordpress\htdocs\wp-content\plugins\40mtest\40mtest.php on line 288

THESE LINES BELOW ARE PERFECT
$aa_panel->createOption( array(
'name' => 'User Role Access',
'id' => 'aa_general_role',
'type' => 'multicheck',
'desc' => 'Which User Roles have Access to website - Administrators always have access',
'options' => array(
// '1' => $option_wp_roles_string[0],
'1' => $option_wp_roles_string[1],
'2' => $option_wp_roles_string[2],

undefined offset is generated when you try to access an array with an invalid index, so the problem is that the array "$option_wp_roles_string" doesn't actually have 10-13 items. Perhaps you can generate the options automagically using a function above and then simply include them like so:]
'options' => $my_generated_options,
