Good Day - I am very new to AutoIt - have gotten through a few scripts already and have decided to progress to the next level... FTP. Below is a script I wrote - gets to line 25 - the MsgBox with the "A","Upload..." and the error message is the box is -1 and the extended is 12018. My questions are: where/how does one easily decipher these message numbers and does anyone have ideas why I am getting these error messages? Unfortunately I cannot post the server/un/password due to security reason
