Hello,

we´ve just started using Epidata and we´re really happy with it, but we also do have a big problem with the MISSINGVALUE command, which we´re not able to solve. It has already been mentioned in the archive in December, but the answer to it didn´t really help us.

We´re trying to use different missing values for different variables (e.g. 9 8 and 99 88 and 999 888) in one file. But the checkfile commands keep on disappearing, sometimes immediately, sometimes they work for some time and disappear later. Sometimes they´re there in the checkfile, but do not work, when we try to enter data.

I´ve already tried to partition my file and use the RELATE function, to make sure the checkfile is not too long (they´re far less then 1000 lines now), but the problem persists. The problem also occurs working with version 3.1 as well as with 3.02.

Would be great, if somebody could help us. Thank you in advance!
