My team and I are beginners with SPSS.
We created a database with 237 patients & > 400 variables. We noticed that from time to time, when we added data, the database would corrupt i.e entire rows would disappear and numbers would be replaced by other numbers that made no sense or replaced by ''?'' inside a black lozenge symbol.
At first, we simply opened a prior version of the database and restarted adding data from there. However, now that we are beginning our statistics, we are unable to add new variables without getting this error. Duplicating the master version and restarting our work from there does not solve the problem.
Does anyone have any advice for us? We'd try anything before having to recreate our database from scratch...
