Ducks-- Thank you thank you thank you....
I thought it had to be a file, but there the index file was with tons of references to the deleted files. At one point sigil didn't allow links to work, so I assumed that they wouldn't but after being fixed now they do...Hooray!
Now if I could only get rid of my <center> troubles life would be grand. <center> is the way I have centered * * *, (what works in my Sony) but the validation doesn't like it. I will probably have to change them all to a class with giant left and right margins, but I am still swatting errors in the text.
