  Hi,
  
  I have begin a Theme Select Block.
  
  It works at 90% as you can see at top right of
  
  http://imagicweb.com
  
  I have a problem with retrieving the current URL, as the "thelang.php" block does
  
  I have tried to use the "thelang.php" way of calling the currentURL, but it has not worked for me.
  
  Can someone help me to finish this block?
  
  THANKS!
  
  copy, save as themes.php and put in includes/blocks
  go to the blocks admin panel, new block - > Core/Select Theme
  enjoy, and... report bugs! (or help)
  
  

  Code
