# [Tutor] Help with this script

```Hi guys, I am back from my hols.

Jacob S gave me this little exercise to do a little while ago.

1) Make a program to compute the areas of several figures. Make it display a
menu on startup,         ask for a choice, and then compute the area of the
figure chosen by asking for dimensions.

2) Make another script similiar to #1 using volumes instead of areas

I have decided to merge the 2 scripts. First I should have a menu asking me
if I want to compute areas or volumes. Then depending on the choice it
should display the relevant menu. My first menu comes on but if I select "b"
or "c" the script does not run. The error message points out that
"print_options()" or "print_options_2()" are not defined. Could somebody
point me into the right direction, thanks.
