Using the following .qes and .chk files with EpiData version 3.1, EpiData's behavior is strange:

If I use the [-] numeric key to enter missing values in the field "schtype", EpiData jumps to the field "male" (i.e. "class" receives no focus). If I use the [-] key in field "male", EpiData issues the error message "'-' is not a valid floating point value" although missing values are defined.

The problem seems to be the movement to the next field after using the [-] key, because if I drop field "coder" the problem of field "male" does not occur.

Is there a problem in the check file I did overlook or is this a problem of EpiData version 3.1? Are there any solutions/suggestions?

BTW: Unfortunately, if I want to label the missing values (an important feedback to the coder in case different types of "missingness") I cannot utilize the facility of EpiData to use the [-] key for entering missing values, because I cannot (better: should not) use COMMAND LEGAL and MISSINGVALUE with overlapping sets of values for the same field. This underscores the importance of the suggestions in my last mail (July 1, 2005) to the list.

Here the code of the .qes and .chk files:
