Adding a multi-timeframe instrument via variable integer vs. absolute integer

[Shansen]

All,

An interesting anomaly in adding a multi-time frame instrument using the standard

Add("^SP500",PeriodType.Minute,5);

versus

Add("^SP500",PeriodType.Minute, Period); 
   where "Period" is defined in the variables region as "private int Period = 5;

Where the absolute "5" period is used all behaves as expected, with the following code showing the 15min Primary dataseries updating and the added 5min Secondary dataseries updating each 5mins. Where the variable integer "Period" is used the below code shows the 15min Primary dataseries updating and the added 5min Secondary dataseries updating each 1min.

if (FirstTickOfBar)
{
  if(BarsInProgress >= 0 && BarsInProgress <= 3) 
  {
    Print (BarsInProgress + " - " + Time.ToString() 
  }
  else
  {
    Print("Unexpected value for BarsInProgress: " + BarsInProgress);
  }
}

Any ideas are welcome.

Regards
Shannon
