Array output question

[Hydrowizard]

Hi all, I?m trying to understand arrays. Please could someone explain to me why
the first is ok and outputs 'Second' but the second example produces an error
as it is a complex variable. Why is the first example ok the second not?
<!---example1---> <CFSET aryTemp = ArrayNew(2)> <CFSET aryTemp[1][1] = 'First'>
<CFSET aryTemp[1][2] = 'Second'> <CFSET aryTemp[2][1] = 'Third'> <CFSET
aryTemp[2][2] = 'Fourth'> <CFOUTPUT>#aryTemp[1][2]#</CFOUTPUT> Outputs
'Second' <!---example2---> <CFSET aryTemp = ArrayNew(2)> <CFSET aryTemp[1][1] =
'First'> <CFSET aryTemp[1][2] = 'Second'> <CFSET aryTemp[2][1] = 'Third'>
<CFSET aryTemp[2][2] = 'Fourth'> <CFOUTPUT>#aryTemp#</CFOUTPUT> Gives Error
Thanks for any advice!

To see the whole array structure, you can type <cfdump var="#aryTemp#">,
but you can't just use output to see the whole thing. To do that, you
need to loop through each value in turn and for a two-dimensional array
you need one loop nested inside the other.

Hi

the error itself is saying that the complex values can't be displayed using
the cfoutput.

Queries, arrays, and COM objects are examples of complex values.

so we can't display these values. but as in the first example we can display
the individual value of that complex variable.

The array does not contain a value in itself to display, but rather is a
reference to an area of memory that contains values. You have to use the array
notation to reference a particular value to display.
