1 | local User = script.Parent.Parent.TextBox |
2 | script.Parent.MouseButton1Click:Connect(function(player) |
3 | print(User.Text) |
4 | end) |
There's an important distinction to be made between what local User = script.Parent.Parent.TextBox and local User = script.Parent.Parent.TextBox.Text do in the code.
The first does a single action, it stores a reference to script.Parent.Parent.TextBox.
The second does two actions. First, script.Parent.Parent.TextBox.Text access the property of the TextBox. This is a string. Then it stores the variable. So the user variable in the second statement only stores the string, it does not keep a dynamic link to script.Parent.Parent.TextBox.Text. It stays the same. That's why we access the property in the event connection instead.

Instead of:
1 | local User = script.Parent.Parent.TextBox.Text |
You would do this:
1 | local User = script.Parent.Parent.TextBox |
Then when you were printing the text you would do:
1 | print(User.Text) |
Problem
The problem is one script is assigning a string (the TextBox's Text) to a variable which never gets updated. The script is run remembering the value of the TextBox's Text.
1 | local User = script.Parent.Parent.TextBox.Text -- ==> "" (String) [It's an empty string.] |
This result gets remembered in the script and when your event executes, you're telling it to print out that remembered result. Which would be an empty string.
Solution
You can do this in a variety of ways. You can change the script to how you have it where it goes through the TextBox and Text property directly, or you can reference the TextBox as an object prior to your event and reference the object to get to the Text property.
1 | local User = script.Parent.Parent.TextBox -- ==> TextBox (object) [It's a reference to the object you have set up.] |
2 | script.Parent.MouseButton1Click:Connect(function() |
3 | print(User.Text) |
4 | end) |
