RE: Filtering out dead stocks

["michael" <mslist@xxxxxxxxxxxxxxxx>]

I'm not sure why you would get the errors in your columns...  I am attaching
the formula files so you can directly import my exploration.  I would be
interested to know if you still get the error after using the import.

The "test=1" is not necessary.  In fact the test variable is not necessary.
However, I use this method as a programing technique because it is more
discriptive and unmistakeable.  Also, in the past I have had some problems
with True/False statements not working as expected, this just clarifies my
formula and doesn't really have any additional overhead for the computer to
process.

when I entered the items in Col A, B, C, I got an error message.

when I just entered the items for the filter  (nothing in any of the other
cols) it worked.

Is the last line of the filter formula "Test=1" necessary?

I was able to locate some errant securities and delete them.

thanks for your help.
