*Hello*

*Just wondering if you have some time to cast your eyes over another
basic program.*
Donald pointed out the first error. (actually there are 3 such spelling
errors).
When you get "name xxx is not defined" use your editor's find feature to
find where the name is defined. In this case you would not find it which
should lead you to the problem.
When you fix that you will then get
TypeError: 'str' object is not callable
on the same line of code.
Do you see why?
When you fix that you will then get either
ValueError: invalid literal for int() or
ValueError: int() base must be >= 2 and <= 36
Before returning with "why" attempt to apply the error message to the
code to see what the problems are.
Look up int() in the Python documentation

*My way of thinking is firstly I need to fix line 29 which is main(),
I tried to do this by adding the brackets around text output in line
26. This seemed to allow me to type main against margin rather than it
wanting to indent but didn't fix the problem. Your suggestions would
be appreciated.*
