LMSSetValue Error: Incorect Data Type

Any ideas on what causes this type of error? I also then get the error: "Some of the persistent data was not able to be stored"

I have worked with Support at Trivants who is great, but I still cannot clear this error. I have tried all the suggestions they offered but I just can't get this one figured out.

My course is set up as such:

4 main sections with sub chapters as lessons

internal reviews set up with Survey questions

3 main tests

All set normally no customization and all questions are either T/F or multiple choice. I have turned off all retain data between sessions, which I actually need to keep but one of the support suggestions was to turn / uncheck that option.

Did it still having errors on end of 3rd test.

I am not keeping the score only the completion status.

However, I can't get this error to not appear. All suggestions and information greatly appreciated. This course is due in 4 days.

Thank You
