I would like to keep a variable (numCustomers) totally undefined until I end up with a final formula like f(numCustomers). I end up with a formula at the end, however, the plot breaks. I am probably just not aware enough of how mathematica works.

I have issued the following commands:

Assumptions
numSunaPerCustomerAvg = 5
numIntrusionsPerDayPerSunaAvg = 10
numClonedPacketsPerIntrusion = 100
clonedPacketSizeAvg = 100
CDFPercentage = 0.99

Calculations
numSuna = numSunaPerCustomerAvg*numCustomers
numIntrusionsPerDay = numSuna*numIntrusionsPerDayPerSunaAvg
numIntrusionsPerSecond = numIntrusionsPerDay/3600/24
dist = PoissonDistribution[numIntrusionsPerSecond]
CDFnumIntrusionsPerSecond = Quantile[dist, CDFPercentage]
CDFPacketLoad = CDFnumIntrusionsPerSecond*numClonedPacketsPerIntrusion
CDFBytePerSecondLoad = CDFPacketLoad*clonedPacketSizeAvg
CDFBitsPerSecondLoad = CDFBytePerSecondLoad*8
Plot[CDFBitsPerSecondLoad, {numCustomers, 1, 10}]

And get the following output:

\!\(80000\ Quantile[PoissonDistribution[numCustomers\/1728], 0.99`]\)

Plot::''plnr'': ''\!\(CDFBitsPerSecondLoad\) is not a machine-size real number \
at \!\(numCustomers\) = \!\(1.000000375`\).''


with a few more error messages after the first Plot error message.

Any ideas?

Thanks
