I'm creating a counter to count how many empty cells there are when a user uploads a CSV file. I am also using treeview to display the contents of the CSV. The `print("There are", emptyCells.sum(), "empty cells")` works and prints the number to the console but I want to display this in a label so the user can view this in the GUI. It is not displaying anything but a `"row"` is being added to the application after a file has been uploaded where the label should be as everything moves down but no contents are being inserted into the label.

```py
emptyCells = (df[df.columns] == " ").sum()

# print("There are", emptyCells.sum(), "empty cells")

tree.pack(side=BOTTOM, pady=50)
messagebox.showinfo("Success", "File Uploaded Successfully")

stringVariable = StringVar()
printVariable = ("There are", emptyCells.sum(), "empty cells")
#print(printVariable)

stringVariable.set(printVariable)
lbl = Label(windowFrame, textvariable=stringVariable, font=25)
lbl.pack()

```
