search script bug

[crazy8]

Ok I have this search script I have been working on but I have a few issues I have noticed and not sure how to fix them. Here are my issues

 

When page first loads it already displays

Search Error

 

We don't seem to have a search parameter!

Now if I still decide to do a search anyway, then I get this

Search results for: example bakery

 

Any ideas why this is and how to fix it?

Thank you all for the help and keep up the great work.

//select database
mysql_select_db($database_logon) or die ( "Unable to select database!" );

//specify how many results to display per page

// Get the search variable from URL
  $var = $_GET['q'];
//trim whitespace from the stored variable

// check for an empty string and display a message.
