Updating Folder Path - AutoHotKey - scripting

Question

I am trying to figure out how to update a path and I am unsure how to do it and I keep getting some errors.
I need to update the Sample Output that is Displayed on the EV Output. Any help would be great.
As you can see in the image Output sample is updating the selected Input folder. I need it to be the Info that is in EV Output.
Here is my Menu Code
;; MENU

Gui, Add, Button, x7 y7 w110 h30 gInput, Select Input Folder
Gui, Add, Checkbox, x7 y47 w730 h20 checked vCheck1,Include the last folder of the input folder in the output?
Gui, Add, Text, x22 y82 w600 h20 , Output Sample:
Gui, Add, Text, x132 y82 w610 h20 vDisplayPath, %DisplayPath% ;--Line needs to match EV Output

Return
Here is my EV Code
OutputEV:
FileSelectFolder,OutputEV,, 3, Select EV Output Directory For Logs
if OutputEV =
{
MsgBox, You didn't select a log folder. Try again!
return
}
else
Guicontrol,1:,DisplayEV,%OutputEV%
return
I have tried adding like Guicontrol,1:,DisplayOutPutEV,%DisplayOutPutEV% but I get errors. I just need Sample Output to match EV Output and I cant figure that out.
Any help would be great.

Answer 1

At first glance, it seems your issue is with this line
Guicontrol,1:,DisplayEV,%OutputEV%
You've built up your GUI with no identifier, buy you're trying to talk to a control on GUI 1 which doesn't exist. Remove the GUI identifier.
GuiControl,, DisplayEV, %OutputEV%
In your GUI, give your controls DIFFERENT variables
Gui, Add, Text, x22 y82 w600 h20 vlblOutputSample, Output Sample:
Gui, Add, Text, x132 y82 w610 h20 vDisplayPath, %DisplayPath%
Then, in your subroutine, just set both controls' text to the OutputEV variable.
GuiControl,, DisplayEV, %OutputEV%
GuiControl,, lblOutputSample, %OutputEV%
