# [Tutor] All Entry Boxes taking the same value

```Hi,
I am working on a GUI application where I have a multiple number of entry
boxes and I created a loop for the label and entry boxes depending upon the
number of times it needs to be shown. However, I tried assigning different
values to each label and entry boxes in the for loop using lists, so that I
can save different values obtained from the entry boxes in the entry lists
and use them later.

*However, when I execute it, and type something in one entrybox, it shows
in all the entry boxes using multi-cursor option. *

Can someone please tell me how I can avoid this error?
I am trying to put a for loop since I need to create the gui such that the
number of times it needs to be done would be unknown. Hence, the way I went
about this was to take an upper limit of 3 and thus, reacoriginal = [" ", "
", " "]. This can be used as an upper limit and the required number can
thus fit in as needed.
Here, for example, I have taken the required number as two. this would be
later modified.

Code:
from Tkinter import *

root = Tk()
root.geometry("500x350")

# Variables:
reacoriginal = [" ", " ", " "]
conca = [1,0,0]
print conca
concunit = [" ", " ", " "]

concunit11 = StringVar()
concunit21 = StringVar()
concunit31 = StringVar()
conca1 = IntVar()
conca1.set(1)
concb1 = IntVar()
concc1 = IntVar()

average = [" ", " ", " "]
lowest = [" ", " ", " "]
highest = [" ", " ", " "]
averageformulation = [" ", " ", " "]
lowestformulation = [" ", " ", " "]
highestformulation = [" ", " ", " "]

print average
reactants = ["A", "B", "C"]
for i in range(len(reactants)):
Label(root, text = "Experimental Range").grid(row = 0, column = 0, sticky =
W)
labeldown = Label(root, text = "For Parameter Estimation")
labeldown.grid(row = 1, column = 0, sticky = W)
labeldown.config(state='disable')

Label(root, text = "Average ").grid(row = 2, column = 1, sticky = W)
Label(root, text = "Lowest ").grid(row = 2, column = 2, sticky = W)
Label(root, text = "Highest").grid(row = 2, column = 3, sticky = W)
Label(root, text = "Units").grid(row = 2, column = 4, sticky = W)
Checkbutton(root, text = reactants[i], variable = conca[i]).grid(row = 3+i,
column = 0, sticky = W)
optionlist2 = [u'\u03bcmol/L',  'mmol/L','mol/L']
concunitdrop.config(width = 8)
concunitdrop.grid(row = 3+i, column = 4, sticky = W)

for i in range(len(reactants)):
*Entry*(root, textvariable =* average[i]*, width = 15,
state=DISABLED).grid(row = 3+i, column = 1, sticky = W)
*Entry*(root, textvariable = *lowest[i]*, width = 15).grid(row = 3+i,
column = 2, sticky = W)
*Entry*(root, textvariable = *highest[i]*, width = 15).grid(row = 3+i,
column = 3, sticky = W)

root.mainloop()
```
