OnAction attribute error in RibbonXML

[needtechhelp]

I created customized ribbon in Access 2010 by following the instructions here:
<deleted dead link-pbaldy>

After restarting the application, I get the following error:

The attribute "OnAction" on the element '{http://schemas.microsoft.com/office/2009/07/customui}button' is not defined in the DTD/Schema.

Here is the XML:

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">
<ribbon startFromScratch="true">
<tabs>
<tab id = "tbApp2" label = "APP2">
<group id="grpDP" label="Departments">
<button id = "DP1" label="COSTCENTER" OnAction="OpenCCTFrm.OpenForm()')"/>
</group>
</tab>


</tabs>
</ribbon>
</customUI>

I am not having any luck getting a custom button on ribbon tab. I can get it on the QAT.

Here is a thread discussing my early experience with custom ribbon http://forums.aspfree.com/microsoft-...at-303789.html

The example db's helped me get what I wanted.

OnAction="OpenCCTFrm.OpenForm()')" is not right
OnAction="MacroOrFunctionName"
OnAction was to call a macro or sub/function named MacroOrFunctionName

try using:<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
