[Tkinter-discuss] RADIOBUTTON AND BUTTON

[EDWINFMI]

Hy guys
I am testing my script, but something weird happend with this script.
When i was running the script with the command print at the end of the
function calculation, i got a good result , this means that my script is
well done, but whe i am using the command return i can not define a value by
using my button execute and always this script is printing a result before
the execution.
The main idea is to select a option and after that to execute a conditional
with fornulas inside.

thanks in advance
