paypal problems

i was trying to buy some beyblades off playmoya and when i got to the payment paypal said "You cannot complete this action on the card you have selected. Please select another card." if anyone knows how to fix this please help
I Had some problem like this can you specify the problem in detail , mine was my debit card was not accepted by paypal , it really depends on the country , & just maybe you might have put the details wrong or maybe your bank is not officially supported by paypal
Try again if it does not clearly mention the problem take a screenshot , hide your important details by usingpaint brush & add black color or whatever or use photoshop then send the screenshot to paypal they will reply , mostly i doubt they will tell you to contact your bank
