If function

Hello @luisef

There are some issues in your equation. First, in javascript the operator for equality is the double symbol: “==” because the symbol “=” is used for assignment.

Second, the structure of the “IF” operation is: IF(condition, result if true, result if false)

Furthermore, the IF operations can be nested.

So, your equation can be implemented as follows:”

 
IF(fieldname5==1, "number one", IF(fieldname5==2,"number two", "number three"))

Using the third party operator of javascript:

 
(fieldname5==1) ?  "number one" : ((fieldname5==2) ? "number two" : "number three")

Using the function structure, and the “if” conditional statement (please, do not confuse it with the “IF” operation in the plugin):

(function(){
    if(fieldname5==1) return "number one";
    else if(fieldname5==2) return "number two";
    return "number three";
})()

Using the switch conditional statement of javascript:

(function(){
    switch(fieldname5){
        case 1: return "number one";
        case 2: return "number two";
        default: return "number three";
    }
})()

All previous equation are equivalent.

Best regards.

Grate!
Thank you very much for your attention and rapid response. Simply amazing!
I’ve understood the reasoning and changed it by default to “” instead of “number three”.
That solves totally my problem.
Best regards.
