Dear Aysha,

Not having an ID number is a fatal error that may compromize a lot of stuff
in the analysis. By now U must have figured out that the best strategy would
be a ID number generated by you and have the same ID number on the pair
file. I did the same error and learned making mistakes and having to do all
again sometimes in the past.

I assume that U have the exact same 126 forms digitized twice in differrent
files! If You have them all in the same order somethings can be done to work

The first sugestion, since it seems to bem few records, is to digitize a
third time using the validate double files in the tool menu. (Im not shure
if I can call like this because my menus are in portuguese) At this tool
EpiData creates a second file with the same name with the extension
yourfile_dbl.rec. Enter data in this file and U will see that as U put the
data in the file it will show the difference of th first file and then ask
if want to keep the new value or the old value! This one takes work thouh!

The second work arround that I can imagine is that U may create a new
variable in the qes file that would be the ID, update the rec file, enter
the new unique IDs and the same ID inthe mirror file. A more clever one is
to export your two files to other format such as STATA or xls and then
create a new sequencial variable such as 1 to 126, doing the same with the
mirror file. Watch out for mistakes here, beacause if U do mistakes it may
be hard to find where it is! Then import them again inthe Epidata format an
now compare them! If U work with STATA, it also have tool to compare
datasets. Im shure that SAS and SPSS or R also have similar tools.

I hope it helps you!

Good luck,
Pedro Emmanuel Brasil
