Well I will tell you how to do it with one text field, and for two you would just do it twice. Take for example a table:
CODE
TblEmployees
ID First Last
1 Frank Oz
2 June Jones
3 Bob Smith
You form has two unbound text boxes named "FirstNameBox" and "LastNameBox", and a button named "AddNameButton"
In the AddNameButton's OnClick event, add the following code:
CODE
DIM strSQL as String
strSQL = "INSERT INTO TblEmployees (Name) VALUES ('" & me.FirstNameBox & ", '" & me.LastNameBox & "')"
CurrentDB.Execute strSQL
If you entered 'Jim' into FirstNameBox, 'Jenkins' into LastNameBox, and clicked the button, the result would be:
CODE
ID First Last
1 Frank Oz
2 June Jones
3 Bob Smith
4 Jim Jenkins
