Sub scripted value is neither an array nor pointer nor vector

I am trying to write a code that reads in an item name, quantity and price using a typedef struct, but keep getting this error.

Sub scripted value is neither an array nor pointer nor vector on line 76, 79, 82, 100,101 and 102.

I had the code working before but, when i went to display the inventory nothing would appear.

#include <stdio.h>
#define item 100
#define quantity 100
#define price 100

typedef struct Management
{
char arrayi;
int arrayq;
float arrayp;



}RECORD;

void addToInventory(RECORD one,int *totalItems);
void displayInventory(RECORD one,int totalItems);
void inventorySave(RECORD one, int totalItems);

int main()
{
int x;
int y=1;
int totalItems=0;
RECORD one[100];

while(y==1)
{//begining of while

printf("1. Add to Inventory\n");
printf("2. Adjust Quantity of an Item\n");
printf("3. Print Inventory\n");
printf("4. Remove an Item from Inventory\n");
printf("5. Quit and Save inventory\n");
scanf("%d",&x);




switch(x)//begining of switch
{


case(1):
addToInventory(*one,&totalItems);//function call
break;

case(2):
printf("The user chose to adjust the quantity of an item.\n");
break;

case(3):
displayInventory(one,totalItems);//function call
break;

case(4):
printf("The user has chosen to remove an item from inventory.\n");
break;

case(5):
inventorySave(one,totalItems);//save function
printf("All items have been saved and the program has been quit.\n");
y++;//ends switch

break;

}
}
}//end of main

void addToInventory(RECORD one,int *totalItems)
{


printf("Enter the item being added to the inventory.\n");
scanf("%s",one[*totalItems].arrayi);//item

printf("Enter the quantity of the item.\n");
scanf("%d",&(one[*totalItems].arrayq));//quantity

printf("Enter the price of the item.\n");
scanf("%f",&(one[*totalItems].arrayp));//price

(*totalItems)++;//+1 to total items




}


void displayInventory(RECORD one,int totalItems)
{


int x=0;
printf(" Item Quantity Price\n\n");
for(x=0;x<totalItems;x++)
{
printf("%10s",one[x].arrayi);
printf("%17d",one[x].arrayq);
printf("%13.2f\n",one[x].arrayp);

}





}


void inventorySave(RECORD one,int totalItems)
{
