vbmark on "How to insert data into custom meta table"

Hello,

I have a custom meta table I created named carsmeta. I copied the table structure from another meta table.

How do I insert data into this table? I tried using add_metadata

add_metadata( 'carmeta', 1, "Ford", "Blue" );

but that doesn't work.

Also, what is the best way to structure/format the data for the value?

Thanks!
