Getting "IndexError: Cannot choose from an empty sequence" and do not know why my sequenceis empty

This is the full code The program is supposed to be something akin to a secret santa generator. Person a gives x number of gifts, persin b gives y number of gifts, and they don't get their own back. The problem is I only have very basic experiance with python, and this happened.

import random
number_of_people=int(input("How many participants?"))
list_of_names=[]
list_of_numbers=[]
origional_list_to_use=[]
for i in range (number_of_people):
    name=input("What is the name of person "+str(i+1)+"?")
    number=int(input("How many is "+name+" giving?"))
    list_of_names.append(name)
    list_of_numbers.append(number)
    for i in range (number):
        origional_list_to_use.append(name)
list_to_use=origional_list_to_use
count=0
while count<number_of_people:
    giving=[]
    for i in range (list_of_numbers[count]):
        giving.append(random.choice(list_to_use))
    if list_of_names[count] not in giving:
         print(list_of_names[count]," gives to ",giving)
         count=count+1
         print(list_to_use)
         for giving in list_to_use:
             list_to_use.remove(giving)
    else:
         print("INVALID")
         count=0
         list_to_use=origional_list_to_use

gives an error, but why is my sequence empty? What am I doing wrong here? I'm thinking it may be in my list or use of random?

Sorry, here is the full error bit.
