Create Droplet in Quark

Hi all!

I want to create a droplet, if you drop a (quark) document on the droplet, i want the script to check if this file already exists on the local server, if it does, it only has to show a dialog with the message “This file exists on the server”. Else the message “This file does not exist on the server”. It sounds quite simple to me, but i don’t get it to work :oops: Can somebody please help me! TIA, Fuut
