Variable not defined for "number of trials" ?

Says variable not defined for number of trials for some reason - any
way to correct this?

Private Sub MyFunction()

' this variable holds the number of trials in the simulation

NumberOfTrials = 500

' start the simulation with the desired number of trials

RiskAMP_BeginSteppedSimulation (NumberOfTrials)

' use a loop to run the simulation for the same number of trials

For i = 1 To NumberOfTrials

' any VBA code can be run here; in this example, we do
' a simple calculation on some spreadsheet values.

Sheets("Interest").Select
Range("E28:DI28").Select
Selection.Copy

Range(Selection, Selection.End(xlDown)).Select

My guess at why you are getting this message is because you have your system
configured to add Option Explicit to the top of each code window. This is a
good thing! However, it does require you to declare (using the Dim
statement) each variable you use in your code (also a good thing to do). So,
you need to add this...

Dim NumberOfTrials As Long

(I took a guess, based on the name, that this variable will never be
assigned a floating point value, otherwise I would have used Single or
Double instead of Long in the Dim statement.) By the way, the main benefit
of using Option Explicit is so you can be alerted when you misspell a
variable name later on in your coding. For example, if you declare a
variable as AlertMe, assign values to it and later on when you go to use it
and accidentally misspell it A1ertMe (that is a one instead of an lower case
L) later on, you won't spend days tracking down the error.

Give that this line declares RiskAMP_BeginSteppedSimulation as a variable of
type Long...

Dim RiskAMP_BeginSteppedSimulation As Long

What is this line supposed to be doing?

RiskAMP_BeginSteppedSimulation (NumberOfTrials)

In other words, what do you *think* the NumberOfTrials variable in
parentheses is doing?
