I have combined data from 3 sources on one spreadsheet. The data has been
matched by EE # (same # in from all sources) so all data from the 3 sources
are on the same line for a particular EE #. Columns B through R contain data
from Source 1, columns T through AJ contain data from Source 2, columns AL
through BB contain data from Source 3.

1.) Formula in column A needs to look at data in column B, T & BB.
If there is data all three columns then the cell containing the formula
should be blank.
If there is no data in a column B the formula should return "No data in
Source 1".
If there is no data in multiple columns, the formula should return "No data
in Source 1 or 2", or "No data in Source 2 or 3 or "No data in Source 1 or 3"
whatever the case may be.

2.) I need to varify the data for certain columns plus identify which column
contains different data. Source 1 is the standard to measure the other
sources against. The data contained in column E from Source 1 should be the
same as column V from Source 2 and column AP from Source 3. A formula in
column BC needs to look at the data in E and compare the values of V and AP,
if either has a value different from the value in column E the formula needs
to return €œValue from Source 2 is different€� or €œValue from Source 3 is
different or €œValue from Source 2 and 3 are Different€� or €œNo value in
Source 1€� whatever the case may be.

I tried to evaluate using 2 sources, but ran into problems
If((B30)*(T3=0),€�Data in Source 1, but not in Source 2€�, €œ €œ) worked, but
it references only the 2 columns.

However, If((T30)*(B3=0),€�Data in Source 2, but not in Source 1€�, €œ €œ) does
not work. Again I am only referencing 2 of the data sources and I need to
compare all three.
