...input type='hidden' name='sqlc' value='$SQLCommand'

If your script is for general consumption, I hope you're using -T and are untainting $SQLCommand. Otherwise, someone can slip something truly evil into your SQL stream.

I recommend that you use bind variables in the query, like 

  $SQLCommand = <<SQL;
  SELECT Client, Product, License, Issue, Data, Id, Call
  FROM support
  WHERE Client LIKE ?
    AND Product LIKE ?
    AND Issue LIKE ?
    AND Cause LIKE ?
    AND Call LIKE ?
    AND SupportDetails LIKE ?
  SQL

Then, when you execute the prepared query, you can wrap the variables. You'll need some logic to do it, so that you don't end up with '%%' if the variable is "". I do something like 
  $sth->execute(like_arg(1, $Client, 1),
                ... etc ... );

I'll leave like_arg() as an exercise.
