I'm having trouble uploading a simple date comparison rule. Within the CRF the two variables are both dates and within the rule I am using this I_DATE_MSDIAGNOSIS lt I_DATE_MSSYMPTOMS.
However, upon uploading this rule I see the error OID is not Valid, The OID can only be made of A-Z_0-9 and The Rule you are trying to reference does not exist or is Invalid. The OID is correct.
Please refer to the attached screenshot for more detail.
Thank you for any help.
