Hi
in body email i attached the statements as follow but still as it is in the email view with $ signs
Should i use brackets? I m not a developer & try to learn how to
For Name and Assigned to I don’t recognise those variables.
For assigned to I would put $acase_assigned_user_name
For name i’m not 100% sure what you are trying to show? the account name or the contact name etc?
I try to show the case name as case reference & who is assigned to or dedicated person to finalize
This email works only for High cases that require manager interfere
I would personally user $acase_assigned_user_name for the assigned to
To display the case name use $acase_name
If this works/doesnt let me know and i will look into it further 
Currently you have Subject set as the account name of the case what confused me 
It confuse me as well
Check that
Yeah you have to decide what you want to show.
Currently you have subject: pointing to the account name.
You could set Subject as $acase_name - This will give you the name of the case
And rename Name to Account: and set the variable as $acase_account_name - This will display the account connected to that case
