What is wrong with this XML Ribbon File

[Mackeral]

The Custom UI Editor isn't making my Ribbons any more.

Here's a small sample. It's run before but doesn't now. It is verified by the UI Editor.

<!-- Compiled from "REPORTING 18.XLSM" on 05/03/20 18:18 -->  
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" >  
    <ribbon>  
        <tabs>  
            <tab id="Macros" label="REPORTS" insertAfterMso="TabBefore" >  
                <group id="DATA" label="DATA">  
                    <button id="DATA_a_DATA_Load" label="a_DATA_Load" onAction="DATA_a_DATA_Load" />  
                </group>
            </tab>  
        </tabs>  
    </ribbon>  
</customUI>

Thanks for any help.

Is there a tab called "TabBefore"? I couldn't find any reference to one.

Got it. Thanks for your reply.
