I am receiving the following error with this formula in Crystal XI.

A string can be at most 65534 characters long.

How do I limit the number of characters returned?

Here is the formula that the report is bombing out on.
 
whileprintingrecords;
stringvar x:=x+{Database.NOTES}
 
Type = String and Length is 1000

Do you need to display the full string even if it is over 64K?

You can do this

If Len(x) < 64533 then
   x := x + {Database.NOTES}

If you need to display the full string there are ways using arrays of strings.

I don't need to print if it is over 64. when I use this formula I receive an error: The ) is missing. and it highlights (x)

Did you add that to your formula as shown below.

whileprintingrecords;
stringvar x;
If Len(x) < 64533 then
   x := x + {Database.NOTES}

If it is over 64K then you need to use an array of strings.

whileprintingrecords;
stringvar array x := [""];
numbervar currentindex := 1;

If Len(x[currentindex]) < 64533 then
   x[currentindex] := x[currentindex] + {Database.NOTES}
else
(
    currentindex := currentindex + 1;
    ReDim Preserve x[currentindex];
   x[currentindex] := x[currentindex] + {Database.NOTES};    
);

To display you will need several display formulas
First String
whileprintingrecords;
stringvar array x;
x[1]

second string
whileprintingrecords;
stringvar array x;
numbervar currentindex;
If currentindex > 1 then
    x[2]

thrid string
whileprintingrecords;
stringvar array x;
numbervar currentindex;
If currentindex > 2 then
    x[3]
