Understanding Society User Support

I'm a bit confused to what the variable b_heritage96 is suppose to record. My interpretation is that 0 means people who have not visited any of the heritage sites mentioned in previous questions and 1 means people that has mentioned visiting at least one of these. However, checking my data I found for the b_heritage96 variable 13,598 "0" answers and 9,214 "1" answers (this is applying a filter for b_hhresp_dv=1 since I've join the household and individual response files). The variable h_herfreq has a total of 13,598 answers covering options 1 to 5 which makes me think my interpretation is opposite to what I thought and 0 (in b_heritage96) is people who has mentioned a heritage place and 1 people who has not. Can you clarify please? this changes completely the interpretation of my results and I have a deadline soon.
Thanks.
