I ship Frozen food and can ship up to 4 days via Fedex Ground. I need to have the ground option removed if it's more than the 4 days.

I thought to use zones, but only Flordia comes up on my drop down list so I clearly need a tutorial to use that.

Seems to me that since it's talking to fedex anyway a bit of code the says : if the return data = more than 4 days then the option is removed.

alas I don't know code that well, but I can read and follow directions

Can anyone point me in the right direction?
