Excel Not Responding When Macro Is Ran on a Mac

Hi,
I am having trouble understanding why my macro causes my excel to Not Respond when I run it on a mac. The macro executes perfectly fine when I run it on Excel 2010 on Windows, but for some reason when I run the macro on Excel 2011 for Mac it does not. I attached the workbook that I am having trouble with. The macro that is hanging it up is the DeckOneButtonClick macro (you can run it if you click the Update button on the Deck #1 Percentages spreadsheet). Note that this is literally my first attempt at writing macros, so my code is probably very sloppy. Thanks in advance for any help you can provide... I am thoroughly confused.
