Why am I getting the ReSharper error "The extracted code has multiple entry points"?

I am using the ReSharper to re-factor my code. When I try to move a block of code to the method, I get the following warning:

The extracted code has multiple entry points

Here is the method signature I am planning to use:

private void GetRatePlanComponents(ProductPlan productPlan, 
    ProductRatePlan productRatePlan)    

I searched the web to understand what does it mean. But didn't have much luck. Would someone explain it?

For your reference, here is the code snippet I am trying to move to a separate method:

QueryResult productRatePlanChargeQueryResult = 
    _zuoraService.query(string.Format(@"select Id, Name, IncludedUnits from
        ProductRatePlanCharge where ProductRatePlanId = '{0}' and 
        ChargeModel = 'Overage Pricing'", productRatePlan.Id));

if (productRatePlanChargeQueryResult.size > 0)
{
    foreach (ProductRatePlanCharge productRatePlanCharge 
        in productRatePlanChargeQueryResult.records)
    {
        string numberOfUnits = productRatePlanCharge.IncludedUnits.ToString();

        if (productRatePlanCharge.Name.Equals("Users"))
        {
            productPlan.NumberofUsers = numberOfUnits;
        }
        else if (productRatePlanCharge.Name.Equals("Projects"))
        {
            productPlan.NumberofProjects = numberOfUnits;
        }
        else if (productRatePlanCharge.Name.Equals("Storage"))
        {
            decimal volumeOfStorage;
            if (decimal.TryParse(productRatePlanCharge.IncludedUnits.ToString(), 
                out volumeOfStorage))
            {
                if (volumeOfStorage < 1) volumeOfStorage *= 1000;
                    productPlan.VolumeofStorage = volumeOfStorage.ToString();
                }
                else
                {
                    productPlan.VolumeofStorage = numberOfUnits;
                }
            }
        }
    }
}
