Thank you Alan for your suggestions. I'll continue to muddle on, 
however, I was hoping that this problem might be common and have a 
clever solution.

So far, I search each row for and error and correct it with a random 
number. Of course this can create another error in the same row or a new 
error in a column. Testing and correcting  could continue for a long time.
