Suppress if empty in rule

This will probably be an easy fix. I'm using Acrobat Pro 9.5 and FusionPro Desktop 7.2.

I have a line that contains 3 fields and some spaces (First Name, Middle Name, Last Name. If all 3 fields are empty, I want to suppress that line. But only if all 3 are empty. Since this won't work via just using the setting in the text box I'm trying to do it with a rule, but I keep getting a syntax error (Line 2, it highlights the "!" in "!=". What am I doing wrong?

The goal is to output "First Middle Last" (with spaces between) and only suppress the line if all 3 are empty.

Below is the rule as I have it set up currently:

var NamesOut = "";

if (Trim(Field("First Name"))) != "") {

NamesOut += Field("First Name");

}

if (Trim(Field("Middle Name")) != "") {

if (NamesOut != "") {

NamesOut += Field("Middle Name");

}

if (Trim(Field("Last Name")) != "") {

if (NamesOut != "") {

NamesOut += Field("Last Name");

}

else {

NamesOut += Field("First Name");

}

}

return NamesOut;

Thanks,

I believe you have 1 too many parentheses in line 2

try...

if (Trim(Field("First Name")) != "") {

You could simplify your if statements like this:

var result = "";

result += (Field("First Name") != "") ? Trim(Field("First Name")) + " " : "" ;
result += (Field("Middle Name") != "") ? Trim(Field("Middle Name")) + " " : "" ;
result += (Field("Last Name") != "") ? Trim(Field("Last Name")) + " " : "" ;

return Left(result,result.length-1);

Or you could accomplish the same thing in less code using a for loop:

var names = [Trim(Field("First Name")),Trim(Field("Middle Name")),Trim(Field("Last Name"))];

for (var i=0; i<3; i++) {
   if (names[i] == "") {
           names.splice(i,1);
           i--;
       }
   }

return names.join(" ");

var names = [Trim(Field("First Name")),Trim(Field("Middle Name")),Trim(Field("Last Name"))];

for (var i=0; i<3; i++) {
   if (names[i] == "") {
           names.splice(i,1);
           i--;
       }
   }

return names.join(" ");

You can do it all in one line in FusionPro 8.0 or later:

return [Trim(Field("First Name")),Trim(Field("Middle Name")),Trim(Field("Last Name"))].filter(String).join(" ");

You can do it all in one line in FusionPro 8.0 or later:

return [Trim(Field("First Name")),Trim(Field("Middle Name")),Trim(Field("Last Name"))].filter(String).join(" ");

Now, that's fancy!
