2 fields into one

Question

Hey guys,
was hoping you could help me out here. is there a way for information from two different fields to copy over into one. I do mass amounts of rebate applications and the application form has the first and last name seperate so i enter then in two different fields. I have a 2nd page that i use as a cover page that has the customers name and address so i want to have the first and last name from the previous page transfer to one field on the cover page. is this possible?
Thanks

That code will combine 2 fields with a space separater but it will add a leading or trailing space if there is only one non-empty field and fill the field with a space if both fields are empty.
The following function will combine upto 3 fields and use an optional separater but will not add any leading or trailing blanks if any or all of the fields are empty or null.
// Concatenate 3 strings with separators where needed
function fillin(s1, s2, s3, sep) {
Purpose: concatenate up to 3 strings with an optional separator
inputs:
s1: required input string text or empty string
s2: required input string text or empty string
s3: required input string text or empty string
sep: optional separator sting
returns:
sResult concatenated string
// variable to determine how to concatenate the strings
  var test = 0; // all strings null
  var sResult; // re slut string to return
// force any number string to a character string for input variables
  s1 = s1.toString();
  s2 = s2.toString();
  s3 = s3.toString();
  if(sep.toString() == undefined) sep = ''; // if sep is undefined force to null
assign a binary value for each string present 
so the computed value of the strings will indicate which strings are present
when converted to a binary value
  if (s1 != "") test += 1; // string 1 present add binary value: 001
  if (s2 != "") test += 2; // string 2 present add binary value: 010
  if (s3 != "") test += 4; // string 3 present add binary value: 100
  /* return appropriate string combination based on
  calculated test value as a binary value
  switch (test.toString(2)) {
  case "0": // no non-empty strings passed - binary 0
     sResult = "";
  break;
  case "1": // only string 1 present - binary 1
     sResult = s1;  
  break;
  case "10": // only string 2 present - binary 10
     sResult = s2;  
  break;
  case "11": // string 1 and 2 present - binary 10 + 1
     sResult = s1 + sep + s2; 
  break;
  case "100": // only string 3 present - binary 100
     sResult = s3;
  break;
  case "101": // string 1 and 3 - binary 100 + 001
     sResult = s1 + sep + s3; 
  break;
  case "110": // string 2 and 3 - binary 100 + 010
     sResult = s2 + sep + s3; 
  break;
  case "111": // all 3 strings  - binary 100 + 010 + 001
     sResult = s1 + sep + s2 + sep + s3; 
  break;
  default: // any missed combinations
     sResult = "";
  break;
return sResult;
// combine two fields seperated by a space; optional 3rd field is a null string;
event.vlaue = fillin(this.getField("First Name').value, this.getField("Last Name").value, "", " ")
