Trying to post on wanted section it's asking for a price also when I put in how many items it says 1 item is too short surely this can be made easier so I gave up . When it was items for sale or wanted I understood it now I'm lost .

It likely means the description is too short.

 

Simply enter the maximum price you want to pay and how many you are looking for.
