What does this error men?

I'm building a store that can be seen http://www.moralgenius.com/shop/ here .  Everything seems to be working O.K. except for one entry in category navigation.  When one clicks on the first item in "Categories" at the top of the left panel it generates the error below.  None of the other links seem to have this problem.  I should probably mention that I'm not the stud coder I was when I was young and first got involved with computers, (back in the '60's).  If anyone knows why I'm getting this error and appreciate the help.

Server Error in '/shop' Application.

Please disregard.  I finessed it by creating a "New" category and unpublished the problematic one.  Works fine now.

this would appear to happen if you update a category item with the database directly not using the admin page.
i am not able to find any other tables connected to this any questions how I may upload the categories without using the admin page.

That was definitely not the case.  I was working through the backend and not directly with the database.  In any event, I figured a way around it.

It means that entered wrong 'Price range' value. It can't be parsed. Separate ranges with a semicolon e.g. '0-199;200-300;301-;' (301- means 301 and over)
