below is the relevant section of my code
entry1 = TkEntry.new(root) {
}
entry2 = TkEntry.new(root) do
  show '*'
end

variable1 = TkVariable.new
variable2 = TkVariable.new

entry1.textvariable = variable1
entry2.textvariable = variable2

variable1.value = ""
variable2.value = "Enter any confidential value"

@myVar = TkVariable.new
@entry1.textvariable(@myVar) #<=givbes undefined method
@myEntry = @myVar.value

entry1.place('height' => 25,
            'width' => 150,
            'x' => 10,
            'y' => 10)

entry2.place('height' => 25,
            'width' => 150,
            'x' => 10,
            'y' => 40)
Tk.mainloop

@entry1 specifies an instance variable in a class and is not defined in
your code. Has probably the nil value.

I believe that it's not a good design to process the value of an entry
field when it has just been typed (if possible with tk ?). Usually, you
grab the value when an OK button has been clicked.
