Morning all.
I'm not sure this is the correct place to post my question, so if it's not, 
please let me know, and I'll move it over to the Excel newsgroup.

I'm using the Custom UI Editor to create a ribbon menu for my Excel 2007.
So far, it's been working real well-- I've been using it for over 18 months 
now.
I want to make some modifications to it, and have hit a snag.
The snag is that I was using this particular grouping as a menu and want to 
change it to a gallery. 
I had originally tried making it a gallery but the button control would not 
work-- I kept receiving an error that stated the button was not the right 
element to use; or that I could only use the button command within the 
gallery once, and it had to be at the bottom. Since it's been a while, I 
tried again-- forgetting the original troubles I had then-- and found the 
same error. 
I looked up the 3 part Ribbon tutorial on the MSDN library, and pulled a 
copy of the code they use for the insert month gallery sample. I tried 
duplicating it, and in my version-- with and without the onAction in the 
Gallery, and the Button at the bottom, I get multiple "OnAction not declared" 
errors for my item controls.
Thus-- I don't understand now where I've gone wrong, and am simply stuck. 
Your helps are appreciated. 
Thank you.

My XML code is below.
