U ship - What am I doing Wrong?

[AngliaGT]

I was making a listing to get the MG short block here from Grass Valley,CA.
I'm not in a big hurry,so I put August 7th as the pick up date & August 29th as the
latest pick up date,with delivery on August 14th to the 27th,& it comes up "Invalid Range".
I'm not in a big hurry,but I need to put something down for the dates.
What am I doing wrong?.

Maybe your last pickup date is after your last arrival date.

Solved! I called the guy who has it in his shop &
he talked me through it.
I've received a few bids so far,but way out from what
I'm willing to spend.
