Conditions controlled which  questions are visible. The general syntax was SGQA operator Value, like 111X2X3 == "Y". Conditions could be ANDed or ORed together, but mixing ANDs and ORs was difficult. The conditions themselves were stored in a separate table, and large portion of LimeSurvey's code was devoted to managing Conditions. Because of extensive database access, processing large numbers of conditions could cause noticable performance problems. Furthermore, once you had conditions assigned to questions or groups, you were often not allowed to re-order or delete them.
