Here are the steps I'm taking:
Open Database
Open Table
Select Alter Table Structure (or click F6)
Use slider bar to go to bottom of Structure table.
Click on empty bottom row
Type Field Name -tab over- type Datatype -tab over- type Length -tab over 8X- type Field Name -tab over- type Datatype -tab over- type Length -tab over 8x- …..
After I have added some fields, I will invariably be called away, if I click the close box my changes will be lost and it tells me this, so I click the ALTER TABLE button. It processes for a few minutes then pops up the error message.
Let me know if I can help you more.
Thanks,
Mark!
