My sheet has a repeating section for general skills fieldset class="repeating_skills" Note that this all happens to be lower case. I also have a section for Artistic Skills. fieldset class=repeating_skillA" This has one capital character. Some code that was working for the first, was not working for the second. I finally figured out that log( getAttrByName( this.charID, "repeating_skillA_-KLobDO-llFtZkJqZjFH_SKA_Name")); log( getAttrByName( this.charID, "repeating_skilla_-KLobDO-llFtZkJqZjFH_SKA_Name")); log( getAttrByName( this.charID, "repeating_skilla_-KLobDO-llFtZkJqZjFH_ska_name")); gave "Error: No attribute or sheet field found for character_id -JvAdIYpXgVyt2yd07hv named repeating_skillA_-KLobDO-llFtZkJqZjFH_SKA_Name" undefined "Bone Carving" "Error: No attribute or sheet field found for character_id -JvAdIYpXgVyt2yd07hv named repeating_skilla_-KLobDO-llFtZkJqZjFH_ska_name" undefined Namely, when calling getAttrByName() you MUST lowercase the name of the repeating section, but you CANT lowercase anything else. Only lowercaseing the repeating section name and nothing else avoids the error. This is inconsistent. It can easily be made to work if it is well documented (which it was not). It would be better if the inconsistancy was not present.
