last fm api search issue (no knowledge of last fm api needed..) [Archive]

hello there,

I'm working on a simple implimentation of the last fm api for a school assignment, I have a problem using a search function to search users within the last fm platform.
You can search for a user just fine, but when you want to search for another one, nothing happends. I sort of need to reset the whole search function when a new search is being done.

Here is an example of the current website (try not to mention the bugs :P)
http://stap.iam.hva.nl/~wullem01/eindopdracht/lastfmgame.html (http://stap.iam.hva.nl/%7Ewullem01/eindopdracht/lastfmgame.html)

try using the search [omgnoseat] for my account. Now try another search and youll understand my problem.
There also is a problem when the user your searching for doesnt exists, I don't know how I should cancel the search when no user is found.

any help would greatly be appreciated, I need to finish this in 2 days haha.
Thanks in advance
