Multidimensional array issue

[HENRY LOWE]

Thanks to all for your excellent discussion and suggestions.

To briefly restate the problem:


If tArray[=E2=80=9Cstatus=E2=80=9D] does not contain a value

and

If tArray[=E2=80=9Cstatus=E2=80=9D][=E2=80=9Ctext=E2=80=9D] contains a =
value


How do I determine if tArray[=E2=80=9Cstatus=E2=80=9D] contains a value?


In the message box:

put "data" into tArray["key1"]["key2"]; answer the value of =
tArray["key1=E2=80=9D] - returns EMPTY (so this works)

put "data" into tArray["key1"]["key2"]; answer tArray["key1=E2=80=9D] is =
empty - returns FALSE (it should return true IMHO)=20

put "data" into tArray["key1"]["key2"]; answer tArray["key1=E2=80=9D] is =
an array - returns TRUE (so not helpful)=20
