Source Mod for Item_Inventory

[Radian]

Greetings everyone, Im here to ask for help regarding on my issue on this custom source modification.

This is the part where its getting errors. for the specific part (data = itemdb_group_exists(opt_id);)

		if (sd->inventory_data[i]->flag.inventory_script_option) {
			int j;
			struct s_random_opt_data *data;
			current_equip_opt_index = -1;
			for (j = 0; j < MAX_ITEM_RDM_OPT; j++) {
				short opt_id = sd->inventory.u.items_inventory[i].option[j].id;
				if (!opt_id)
					continue;
				current_equip_opt_index = j;
				data = itemdb_group_exists(opt_id);
				if (!data || !data->script)
					continue;
				run_script(data->script, 0, sd->bl.id, 0);
				if (!calculating)
					return 1;
			}

While recompiling my files these are the message that i get;

status.cpp: In function ‘int status_calc_pc_sub(map_session_data*, e_status_calc_opt)’:
status.cpp:4213:31: error: cannot convert ‘s_item_group_db*’ to ‘s_random_opt_data*’ in assignment
