Force the First Character in a Field to be Capitalized

// This rule forces the first character of a field (typically a field that contains a name) to be upper-case.

var currentField = Field("FullName");

splitFieldVar = currentField.split(" ");

newVar = ""

for (i = 0; i < splitFieldVar.length; i++)

{

newVar += splitFieldVar.substring(0, 1).toUpperCase() + splitFieldVar.substring(1, splitFieldVar.length).toLowerCase() + " ";

}

return newVar;

It may also be easier to use the function:

return ToTitleCase(string);

Hello,

I need a rule to forces :

- a name field to be in lowercase

- and the first caracter in uppercase

How to make it ?
