I am a begginer in EpiData. I don't understand the syntax for doing the following task in the check file:
If var1 = 1 , then I need the field of var10 in the "data entry form" to be locked.
How do I do this?
I tried: var10 BEFORE ENTRY IF (var1=1) THEN HIDE var10 ENDIF END END
But it does not work
Thanks for your help
