I am VERY new to web design, so I apologize in advance for being ignorant.  I am trying to learn!

I had inserted a spry menu bar that looked fine and even tested fine!

I subsequently tried to split a section of my table in the web page in order to have 3 columns of centered text.  The first time I did this, the spry menu bar became vertical even though it is listed as horizontal.  I looked up a forum answer, copied the code from the suggestion, and that seemed to fix the problem (although I still don't know what EXACTLY happened)

I tried to split the table again (I had undone everything prior to this), only this time, the spry menu bar is located outside the page in the left hand corner where my background (I have a wrapper) is.  I tried opening another page where I already had a nice spry menu bar, and it did the same thing!! This makes me think it is the CSS sheet for the menu bar that was modified somehow when I split the table.  I'm pasting the CSS here below, so if anyone sees any issues that might cause this problem, please let me know!! I have been working for the most part in design view, and haven't really modified the code other than to put a wrapper in and a facebook like button, which I've now lost in the slitting cells catastrophe.  Thanks in advance!!!
