Placing Tkinter objects in a dictionary

[Adonis]

I have a loop creating Tkinter objects (an Entry text box) all with the same
name and placing its instance in a dictionary: i.e:

for x in range(10):
    myEntry = Entry(frame)
    myEntry.grid(row=x, column=0)

    someDict['%s'%x] = myEntry

now I have another function which will modify myEntry:

def someFunc(x, data):
    someDict[str(x)].config(text=data) # here is my error; the config does
not work;
                                       # no error is raised.

any help is greatly appreciated.
