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 arround.
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

Hello
I have entered my data twice on epi data and would now like to validate files to make sure that my data is accurate. I have different ID numbers so can not run on Id keys but I have entered the data in the same order so the record numbers match. I have 1 deleted record in one database which I have adjusted for but checking the box that says ignore deleted records. I have 126 records in total when I go to validate files it comes up with an error box saying that it cannot create log file.
Does anyone have any ideas on how this could be fixed.
Thanx aysha

Hi, I would like the stats I get when doing an epitable to to reflect a 90% CI, instead of the default 95%. Is it possible to do so, and if yes, how?
Thanks!
