Help with If Statement

I'm currently trying to write a script that reads a column from my data table, and runs a different set of functions depending on the value of that column. For example,

 

If the data in Column A = A, create a new column called "A" and run the functions (A to C) below.

If the data in Column A = B, create a new column called "B" and run the functions (D to F) below instead.

Else, create a new column called "N/A".

 

When I run my script, it will always create the new column "N/A" even if the value is "A" or "B". It will also not run any of the functions I have written for the "A" and "B" conditions. I feel like I'm missing something very obvious.

 

dt = Current Data Table();

If(
:Column A == "A", dt << New Column( "A", character, nominal ),

Function A

Function B

Function C

:Column B == "B", dt << New Column( "B", character, nominal ),

Function D

Function E

Function F

dt << New Column( "N/A", character, nominal )
)

ScriptingRe: Help with If Statement

If Secretsmight help. Commas separate the clauses in an if statement. Semicolons separate statements within a clause.

You probably want something like this

 

dt = Current Data Table();
If( :Column A == "A", // condition, followed by a comma
     dt << New Column( "A", character, nominal ); // one or more stmts
     Function A(); // with ; separators
     Function B();
     Function C(); // last statement has optional ; and required comma next line
, /* else if */ :Column B == "B", // 2nd condition followed by comma
     dt << New Column( "B", character, nominal );
     Function D();
     Function E();
     Function F() // again, another comma. ; ommited for example...I prefer to use them
, /* else */ 
     dt << New Column( "N/A", character, nominal ) // no more commas, this is the otherwise
);

I like to indent and comment the /* else if */ and /* else */ to make it easier to follow.

 

 

Re: Help with If Statement

Given the scenarios you specified, the script below, generates the 3 cases

     A exists in Column A

     B exists in Column B

     Neither A or B exist

Names Default To Here( 1 );

A = Function( {},
 Show( "Function A" )
);
B = Function( {},
 Show( "Function B" )
);
C = Function( {},
 Show( "Function C" )
);
D = Function( {},
 Show( "Function D" )
);
EE = Function( {},
 Show( "Function EE" )
);
F = Function( {},
 Show( "Function F" )
);

// First Example Column A has the value A
dt1 = New Table( "Example1",
 Add Rows( 1 ),
 New Column( "Column A", Character, "Nominal", Set Values( {"A"} ) ),
 New Column( "Column B", Character, "Nominal", Set Values( {""} ) )
);
Wait( 5 );

If(
 :Column A[1] == "A",
  dt1 << New Column( "A", character, nominal );
  A();
  B();
  C();,
 :Column B[1] == "B", dt1 << New Column( "B", character, nominal );
  D();
  EE();
  F();
 , 
 dt1 << New Column( "N/A", character, nominal )
);


// Second Example Column B has the value B
dt2 = New Table( "Example2",
 Add Rows( 1 ),
 New Column( "Column A", Character, "Nominal", Set Values( {""} ) ),
 New Column( "Column B", Character, "Nominal", Set Values( {"B"} ) )
);
Wait( 5 );

If(
 :Column A[1] == "A",
  dt2 << New Column( "A", character, nominal );
  A();
  B();
  C();,
 :Column B[1] == "B", dt2 << New Column( "B", character, nominal );
  D();
  EE();
  F();
 , 
 dt2 << New Column( "N/A", character, nominal )
);


// Third Example Neither column A has and A nor Column B has a B
dt3 = New Table( "Example3",
 Add Rows( 1 ),
 New Column( "Column A", Character, "Nominal", Set Values( {""} ) ),
 New Column( "Column B", Character, "Nominal", Set Values( {""} ) )
);
Wait( 5 );

If(
 dt3:Column A[1] == "A",
  dt3 << New Column( "A", character, nominal );
  A();
  B();
  C();,
 dt3:Column B[1] == "B", dt3 << New Column( "B", character, nominal );
  D();
  EE();
  F();
 , 
 dt3 << New Column( "N/A", character, nominal )
);

It is my guess, that this is not what you want
