Hi Monks,

Hi have an array of items returned from a dialog box. For most items, I just get a scalar corresponding to the value of the GUI control, but for controls which return multiple values (eg a multi-value list-control or multi-value combo-box) I have an array. How can I tell which is which?

Eg I might get the variables returned with the follwoing values: 

{attributes}{control1} = "abc"  
{attributes}{control2}[0] = "cde"
{attributes}{control2}[1] = "fgh"

[download]
I tried using exist as follows: 
if (exists $dialog->{attributes}[0]){
   ... do something....
}

[download]

But this just gives a error.

I'm sure the answer is obvious, but at the moment it's not hitting me.

Regards

Steve
