GUI Buttons creating text 4 times - autohotkey

Question

I am trying to create my 1st GUI. I just started using AHK today and for the most part have found it very simple to use. I am stuck on one thing though. I created this GUI to display buttons and then depending on what is selected certain text will be typed. When I select the button it is typing the correct text, but it is typing it four times. I have taken off one of the buttons, so there were only three, but it would still type it four times. What do I need to do to make sure it only types it once?

I have not tested it yet, but it could be that your send is initiating this. remember that you first send a keyboard sequence and then hide the GUI, so in your situation the GUI is still active at the moment you send! Try to first hide the GUI and then send or initially replace send by MsgBox to test. You could also first send an !{Esc} to switch the focus back to the previous application before sending your data, That way you don't need to hide the GUI.
OK just tested my assumptions, add the !{Esc} and it works as expected.
