Has any Paypal users had any trouble adding an Amex to their credit cards?

I've been trying to add a Corp. Amex but it keeps getting denied.

I've checked the info. 4 times and I now nothing is wrong with the account.

Help if you can.

Thanks!

It probably will not let you use a corporate AMEX. If you company is like mine, there are several types of vendors (specific codes i.e. jewelry) which AMEX will deny. This is to prevent employees from racking up costs on big ticket items which are not related to the job and thus being on the hook for the costs.
