Concat
Concatenates values.
The Concat function converts each of its arguments to a string and concatenates them together to form the result.
This function returns a String. If there is only one argument, the value returned has the same data type as the argument.
Arguments
| Variable arguments | Add the values to concatenate as arguments. They can be structure elements or functions. | 
Properties
| Join String | Specify the non-breaking space character or characters to be used
                                when concatenating a series of values. For example, ", " would put a
                                comma and a whitespace between each value, or " " would simply use a
                                    space. If any value is null, the non-breaking space character or characters are omitted for that value.  |
