What must you do before you can edit the Member's MGIB election?

Before editing a Member's Montgomery GI Bill (MGIB) election, it is essential to click the "Correct History" button. This step is crucial because it allows you to review and modify any previous elections the Member has made. Clicking this button ensures that you have the correct historical context necessary for making informed changes while preventing any errors that could arise if the existing data is not thoroughly examined. This proactive approach aids in maintaining accurate records and ensures that any changes align with the Member's intents and eligibility criteria.

The other options, while potentially relevant to managing a Member's profile, do not specifically facilitate the correction of election history, which is a prerequisite for editing the MGIB election. Therefore, focusing on correcting and understanding past elections takes precedence in this process.
