adding to a collection -
I'm unfamilar with how to add an item(record) to a collection. I've already established the collection but keep getting errors on the add. My code looks like:
collection.add (
When I put the first ( in place VB opens up this info box listing all my collection elements and their data type. Is it kind of like a sql insert where first you list the field names and then the values?
such as
collection.add (model,year,color) (buick, 98, blue). That does not work nor does it look right. Any assistance is appreciated.
I've attached a print screen (.gif)
