Getting error message I can't find fix for

[Angelus1609]

The error message I'm getting is this :

build/Debug/Cygwin-Windows/_ext/865002671/Random_Card_Dealer.cpp.o: In function `_Z11draw_a_cardv':
/cygdrive/c/Users/Nate/Desktop/C++ Files/Final_Card_Test C++/../CppApplication_2/Random_Card_Dealer.cpp.cpp:57: undefined reference to `select_next_available(int)'

make[2]: *** [dist/Debug/Cygwin-Windows/final_card_test_c__.exe] Error 1
make[1]: *** [.build-conf] Error 2

I've tried finding my mess up in my function but to no avail. Any tips will be appreciated. Thanks

Hi

In your declaration you've got this:

int select_next_available(int n);

But in the definition "available" is misspelt.

int select_next_avalaible(int n)

hope that helps
