Passing a dynamic array of structures to a function

[nickg140143]

Hello,

I have to create a program that lets the user enter how many speakers he/she needs to enter information for,then let them input this information.

I've dynamically allocated an array of structures,and I have written code that will allow the user to specify how many speakers they need to input info in for, that seems to have gone well, however, i'm trying to pass this dynamically allocated structure to a function that will do all that cluttered code, and allow me to call it on multiple occasions.

I seem to be having trouble passing that allocated structure to a function,
below are the two error codes that I will get as well as my code so far,If anyone could help shed some light on this problem for me, It would very much appreciated

Error	1	error LNK2019: unresolved external symbol "void __cdecl EnterSpeaker(struct Speakers *,int)" (?EnterSpeaker@@YAXPAUSpeakers@@H@Z) referenced in function _main	9-11.obj

Your definition is called "EnterSpeakers" but your prototype/call uses "EnterSpeaker".

Im gonna go beat my head in with a ice cream scoop for the next half hour for making that mistake.
