How to set a variable for use later in script

[SimpleScript]

Hi folks- just started playing with thinkscript today, and came up with a script to show the ATR, 10% of ATR & 2% of ATR, with inputs for # of periods (starting at current period price, going backwards) and the type of average (Simple, Exponential, Weighted, Wilders and Hull). It seems to match the TOS provided ATR study at the last candle (which is what I want), and it takes up a lot less screen space, which is the reason for the script.

I have it all working, except when I echo the averageType, it shows a number, which I think is based on an internal conversion the interpreter is doing (Simple = 0, Exponential = 1, Weighted = 2, Wilders = 3 and Hull = 4), when I change inputs in the Customizing Study dialog.

I am trying to build the logic with a variable to display a string that is set, based on the number that averageType contains, but for the life of me I can't get the syntax right... (for example, if the average type = Simple, display "Simple" in the label, rather than the "0" that is displayed)

most recent effort was to declare the DFKTMA variable, and then set it to equal the string I want, using nested If thens, but I can't get even a basic 2 conditional to work.

am I attacking this the right way?

the commented lines are just the last iteration of about 8 different ways I have tried to set the variable DFKTMA to a string that says "Simple", rather than the "0" that is is displayed in the label.

here is the script:

def AvgTrueRange1;
def AvgTrueRange2;
def AvgTrueRange3;
#def DFKTMA = "Simple";


input length = 14;
input averageType = AverageType.WILDERS;
# DFKTMA=Wilders if averageType=0 then DFKTMA==Wilders else DFKTMA==test;

#if (averageType == "3", DFKTMA == “Wilders”, “Test”) ;
# def DFKTMA = "Simple" If (averageType = AverageType.SIMPLE, Else DFKTMA == "test";

AvgTrueRange1 = MovingAverage(averageType, TrueRange(high,  close,  low),  length);
AvgTrueRange2 = AvgTrueRange1 / 10;
AvgTrueRange3 = AvgTrueRange1 / 50;


AddLabel(yes, Concat(" Type of MovingAverage: ", Concat(averageType, Concat("    # of Periods: ", Concat(length, Concat("    ATR: ", Concat(AvgTrueRange1, Concat("    ATR/10%: ", Concat(AvgTrueRange2, Concat("    ATR/2%: ", AvgTrueRange3))))))))), Color.WHITE);

got it figured out, with the help of Pete at Hahn-Tech.
I have a snapshot, but here's the code for anyone interested:

# dec DFKTMA == "SimpleScript";

def AvgTrueRange;
def AvgTrueRange10;
def AvgTrueRange2;

input length = 14;
input AverageType = AverageType.WILDERS;

AvgTrueRange = MovingAverage(AverageType, TrueRange(high,  close,  low),  length);
AvgTrueRange10 = AvgTrueRange / 10;
AvgTrueRange2 = AvgTrueRange / 50;

AddLabel(yes, Concat(" Type of Moving Average:  ", Concat((if AverageType == AverageType.Wilders then "Wilders" else if AverageType == AverageType.Simple then "Simple"  else if AverageType == AverageType.Hull then "Hull"  else if AverageType == AverageType.Exponential then "Exponential" else "Weighted"), Concat("    # of Periods: ", Concat(length, Concat("    ATR: ", Concat(AvgTrueRange, Concat("    10% ATR: ", Concat(AvgTrueRange10, Concat("    2% ATR: ", AvgTrueRange2))))))))), Color.WHITE);

Is it possible to create nested IF like below?

If condition A met then
     if condition B met then
        plot signal = close;
     else
        DoNothing
else
    DoNothing

Basically I need to execute the logic in sequence. Condition 1 -> Condition 2 -> Condition 3.
If any condition is failed (ex- condition 2 then exit the loop and go to next item).
Thanks.

@mitz27 Why not just use "and"...???

If <condition A met> and <condition B met> then plot signal = close else DoNothing;

In your example above you wouldn't have a semicolon anywhere except at the end of the entire logic structure... There are many examples of complex "if . . . then . . . else . . ." and "if . . . then . . . else if . . . then . . . else . . ." conditional structures in Thinkscripts here in these forums as well as in the Learning Center... Specifically, check out the "if" expression... Hope this helps...

Also, you don't put a plot statement in a conditional structure...

@mitz27 The short answer is yes, TOS supports nested if statements. However, as @rad14733 pointed out reserved words such as plot and def cannot be 'nested'. Also, when using a plot statement unless plotting a line, we have to state when to plot and where to plot. Therefore:

def criteria =
if condition A met then
     if condition B met then
        1
     else
        0
else
    0;

plot signal = if criteria == 1 then close else Double_NaN;
