Hi,
Pls check if the filtering attributes is selected only "ap_authority" "needValue" "budgetValue" "timeValue" this four attributes when register the pre-operation update stage,and try the code below:
namespace WeightedBant
{
using System;
using System.Collections.ObjectModel;

using System.Linq;
using Microsoft.Xrm.Sdk;
/// <summary>
/// Base class for all Plugins.

{
ITracingService trace = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));
try
{
trace.Trace("Entering the plugin");
Entity preImageEntity = null;
if (context.PreEntityImages.Contains("PreImage") && context.PreEntityImages["PreImage"] is Entity)
{
preImageEntity = (Entity)context.PreEntityImages["PreImage"];
}
Entity entity = (Entity)context.InputParameters["Target"];
#region Populating Bant Score

var budgetValue = this.GetAttributeValue<OptionSetValue>(entity, preImageEntity, "budgetValue", new OptionSetValue(0)).Value;
var timeValue = this.GetAttributeValue<OptionSetValue>(entity, preImageEntity, "timeValue", new OptionSetValue(0)).Value;
int bantScore = authorityValue + needValue + budgetValue + timeValue;
entity["ap_overallscore"] = bantScore;
#endregion
