Rearranging custom buttons - excel

Question

I am new to programming but I tried to experiment with Excel ribbons. I am using the Custom UI Editor. I wanted to use the insertBefore and insertAfter controls to rearrange my custom buttons. If I do not use a unique namespace and insertAfterQ/insertBeforeQ at button level the order of buttons does not change, however, if I use it I cannot see the related macro (probably due to my namespace), therefore onAction will not do anything after clicking the buttons. I tried various combinations of idQ but I cannot make it work. The below example correctly executes just button 2 which is not in the namespace I specified.
A simple example:
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" xmlns:x="MyNameSpace">
<ribbon>
<tabs>
<tab idQ="x:customTab" label="My Order Form" insertAfterMso="TabHome">
<group idQ="x:customGroup" label="My Order Form Tools">
<button idQ="x:customButton1" label="Clear" size="large" onAction="DeleteOrder" image="deleteorder" />
<button id="customButton2" label="Print" size="large" onAction="ResetOrder" image="resetorder" />
<button idQ="x:customButton3" label="Home" size="large" onAction="NewOrder" insertBeforeQ="x:customButton1" image="neworder" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>
Is there any way to make onAction work within the namespace? Or is there any other way? Many thanks, TS

Do you really need the namespace?
If you want to rearrange your own controls, just switch places in the xml:
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">
<ribbon>
<tabs>
<tab id="customTab" label="My Order Form" insertAfterMso="TabHome">
<group id="customGroup" label="My Order Form Tools">
<button id="customButton3" label="Home" size="large" onAction="NewOrder" image="neworder" />
<button id="customButton1" label="Clear" size="large" onAction="DeleteOrder" image="deleteorder" />
<button id="customButton2" label="Print" size="large" onAction="ResetOrder" image="resetorder" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>
If you want to place your controls relative to built-in controls, use insertBeforeMso or insertAfterMso, like in your "customTab". From what I can tell you only need to use the namespace and idQ-ids if you combine controls from customUI-xml in different files.
