I am working on a form. I changed the name of some "fabrik_internal_ID" elements to names like "Medical_fabrik_interal_ID". I also changed the "Show in table" options for some elements in the same groups to "No". Now when I try to "view data" for that form, I get a page of errors and no data. Here is the first part of the error message: Code (text): getData: Unknown column 'Class_Registrants.Medical_fabrik_internal_id' in 'field list' SQL=SELECT DISTINCT `Class_Registrants`.`ClassRegistrants_fabrik_internal_id` AS `Class_Registrants___ClassRegistrants_fabrik_internal_id` I tried to revert the id's to their original names, "fabrik_internal_ID", but Fabrik will not allow me to use the same name for multiple elements! I also tried to "update database" on the form and got this error: Code (text): amend table: Incorrect table definition; there can be only one auto column and it must be defined as a key SQL=ALTER TABLE `Class_Registrants` ADD COLUMN `medical_fabrik_internal_id` INT(6) NOT NULL AUTO_INCREMENT null AFTER `text_blank_line_9` Then I tried to change some settings in medical_fabrik_internal_id and received the error: Code (text): 500 - An error has occurred alter structure: Incorrect table definition; there can be only one auto column and it must be defined as a key SQL=ALTER TABLE `Class_Registrants` ADD COLUMN `Medical_fabrik_internal_id` INT(6) NOT NULL AUTO_INCREMENT AFTER `text_blank_line_9` Is there a way to fix this inside Fabrik? If not,what do I change in the SQL database to fix this? Thanks.
