[flexcoders] Flex 2.01 type declaration

[candysmate]

Within a function I have:

var tempInactivePriceListArray:ArrayCollection = new
ArrayCollection(mySQLServer.executeQuery(inactiveSql));

However, the Flex compiler complains with:

1008: var 'tempInActivePriceList Array has no type declaration'

I can't see why this should be. Any pointers most welcome.
