I need to create a database that will do a check for data entry. Data
are entered 2x, by two different research assistants and I want to
compare their data entry to make sure each data point was entered
correctly.

I imagine that I need to somehow create a querry where it subtracts
cell A1, Database1 from cell A1,Database2. Anything that does not
result in a zero would indicate a discrepency. I would then want to
create a report that would show me the the discrepencies.

For example:

Item Database1 Database2
1 3 3
2 2 1*
3 1 1
4 2 2


Is this possible? Can the querry I described be done?

thanks,
marc
