Problem Donating Fun Coupons.

I'm trying to donate 1,000 Fun Coupons to Malevolent. But it says its invalid number and don't let me donate it.

Did you type 1,000 or 1000?

I types both. I even typed One Thousand.

I tried donating 1, it says its invalid.

Just tried it on behalf Acheos, it does say it is invaild and wont let you donate.
