Welcome to the forum @Mohamed_Abd_Elazeem
Please note that writing and debugging custom themes and reports is the responsibility of the user. It’s okay for users to ask the forum for help to fix a particular issue but it’s not realistic to expect other forum members to do the full work or a big portion of it. Please refer to forum’s community guidelines for more information.
That aside, the way to make Manager the localization understand your theme is to label your html elements (tags) as follows:
For example, the business name is contained within a <div> tag as follows:
<div style="font-weight: bold">{{ business.name }}</div>
You need to add the id "BusinessName" to it, so it becomes:
<div id="BusinessName" style="font-weight: bold">{{ business.name }}</div>
Try your best at it post your best attempt so other members can help you fix any issues.
