Anything Wrong with this query?

I have been trying to create a report based on this query:

SELECT call_type.call_type_detail, code_city.code_city_detail, area_code.area_code_detail, call_reason.call_reason_detail, cform.cform_phone_number_body, call_outcome.call_outcome_detail, outcome_reason.outcome_reason_detail, cform.cform_date_time , cform.cform_comments
FROM call_type, code_city, area_code, call_reason, cform, call_outcome, outcome_reason

I have verified all fields to make sure they match and when I try to test it CFR crashes...any idea as to why this may be happening? Thanks!
