Utilising a Form 'Help' Callback

Hi,

I am having a little bit of confusion trying to implement a callback function for the 'Help' button in a form/GUI. I have looked at the Cadence Help documentation but I am likely not understanding it correctly. I have attached some simple code below whereby I have a form ( myImageGUI ) and I am trying to execute the myExampleHelpCB() when the user clicks the 'Help' button.

Any thoughts on where I am going wrong?

My end goal is when the user pushed the help button, it will pop up a PDF with the details relating to the specific Skill program.

Thanks,

Keelan

procedure(ImageExportGUI()
prog((cv cw imageView userFilePath userImageType userBGColour myImageGUI)

cv = geGetWindowCellView(hiGetCurrentWindow())
cw = hiGetCurrentWindow()

userFilePath = hiCreateStringField(
?name 'userFilePath
?prompt "File Path:"
?editable t
?value strcat(cv~>libName "_" cv~>cellName "_" cv~>viewName "_Design.png")
);hiCreateStringField

userImageType = hiCreateRadioField(
?name 'userImageType
?prompt "Image Scope: "
?choices list("Entire Design" "Visable Area")
?value "Entire Design"
);hiCreateRadioField

userBGColour = hiCreateRadioField(
?name 'userBGColour
?prompt "Background Colour: "
?choices list("Black" "White")
?value "Black"
);hiCreateRadioField

myImageGUI = hiCreateAppForm(
?name 'myImageGUI
?formTitle "Export Image GUI"
?fields
list(
list(userFilePath 0:0 500:30 90)
list(userImageType 0:35 100:0 90)
list(userBGColour 0:70 100:0 120)
)
?callback "adiExportImage(myImageGUI->userFilePath->value myImageGUI->userImageType->value myImageGUI->userBGColour->value)"
?buttonLayout 'OKCancelApply

hiDisplayForm(myImageGUI)
