Allowing blank answers

[claudia]

Hi,
I wonder if someone could kindly help me with this:

In general I want it to be compulsory for the questions of my questionnaire to be answered (which is already the case, if I'm not mistaken). There are a few exceptions though, of numeric questions which don't have to be filled in if the person doesn't know the answer. One example is asking participants about their weight (Q2). If they don't know it I want them to be able to skip the question rather than enter a wrong weight. How can I do this?

Many thanks,
Claudia

Dear Claudia;
Please try this syntax

Code: Select all

PROC variablename
preproc

	set behavior($) canenter(notappl) on (noconfirm);

a.
