Hi! I understand you’re trying to add money to your CSCPay funds but keep getting the error 24: Invalid Expiration Date. Let’s get this sorted out together.

To start, can you tell me how you’re entering the expiration date? For example, are you typing it manually or scanning a card? Also, what format are you using for the expiration date (like MMYY, MM/YYYY, YYYYMM, etc.)?

In general, this error usually happens when the expiration date on your card is either entered in the wrong format or the card might have expired. Here’s a quick checklist and steps you can try:

1. Check Expiration Date Format: Most systems, including CSCPay, expect the expiration date in the format MMYY (month and last two digits of the year). For example, May 2025 should be entered as 0525.

2. Confirm the Card’s Expiration Date: Double-check the expiration date printed on your card to ensure it hasn’t expired or been misread.

3. Re-enter the Date Carefully: Try re-typing the expiration date, making sure you don’t add extra spaces or characters.

4. Use a Different Browser or App: Sometimes, the app or browser may glitch. Since you're on an iPhone with iOS 18.5, try clearing your browser cache or try a different browser app if using web interface. If using the CSCPay app, restarting it or reinstalling could help.

5. Check Device Date and Time: Make sure your iPhone’s date and time are set correctly, as this can sometimes affect payment processing.

Could you please let me know if you've tried these, and what the expiration date format looks like? This will help me guide you further or suggest the next steps!
