I am developing a program for civil engineering calculations and I have a problem in the result of a Widget Entry, that same Entry is with you in an if condition as shown in the code below, but when I try to use the value typed in that field, the result is always 0. I have tried to collect as String and convert to float, but an error appears that says it could not be converted. The error appears in function confirm1, in the if == 1 condition.
# ...
if Vrd < Vd:
bws = str("Utilize uma largura mínima de viga de %.f cm" % ((Vd / (0.2 * he * fcd)) * 100))
fcks = str("Utilize um Fck mínimo de %.f MPa" % (1.4 * Vd / (200 * bw * he)))

Well, explaining more about my doubt. This program does security checks, if at the beginning states that if the request is greater than the resistor the program must execute the whole (giant) block below. Well in this block is created a new small window that serves only to alert the user that there is an error and conveniently point a solution to the error, the user must enter a new value for the data that will correct the problem (eg. 15cm of the error, but with 18cm is enough, the user can enter the 18cm or a larger value). The problem is that I am not able to capture this new value. And in response to jsbueno, I already tried to use float . And this * 0.01 is simply a multiplication of the captured value (user type in cm and the program does the calculations in m).
