MRSET $Q4 has only one variable

[ft gmail]

Hi,

I use the European Values Study dataset ZA7503_v3-0-0.sav and get the 
error message:

warning: `C:\xxx\ZA7503_v3-0-0.sav': MRSET $Q4 has only one variable.

I don't find any Multiple Response variable set in the file. There is no 
Q4 variable.

How to find and to delete the MRSET ?

Thanks in advance
