There's an occasional problem with the Grade Center that stems from Blackboard somehow labeling two grade columns with the same ID value. The error message depends on the browser, but may look like this:
Internet Explorer:errorParsingDataMsgTypeError: 'this.scoreProvidersMap[...]' is null or not an objectFirefox:errorParsingDataMsgTypeError: this.scoreProvidersMap[spu.handle] is undefinedGoogle Chrome:errorParsingDataMsgTypeError: Cannot set property 'allowContentEdit' of undefined
Using Firefox, follow these steps (can only perform these steps using Mozilla Firefox):
- Go to Full Grade Center
- Click blue "Manage" button and choose "Column Organization"
- Move one column up or down
- Click Submit.
Note: Clicking "Column Organization" won't work unless you are using Firefox. (In other browsers, you can right-click and copy the link in "Column Organization" and paste it into the address bar. But use Firefox, it's much easier with less steps.)
