My Eon Account Was Declined at Paypal

I'm wondering why my eon account was declined at paypal when I tried addiind it to my list of cards. I 've read many posts online that they were able to receive money through paypal. I'm wondering what I did wrong that it wasn't accepted. I didn't deposit any amount to the card though as it is a new one. I suppose this is the reason. I will try to deposit money later and hopefully it will be accepted already. Wish me luck!
