Add a space after the first ')'.
so:
string sqlInsert = "INSERT INTO StudentmemberTable(Fname,Lname,Telephone,Email,Password) "
+ "Values(@Fname,@Lname,@telephone,@email,@password);";
Also make sure your table /column names are correct.
And if that doesn't work try replacing the '@' names with '?', not sure but I seem to remember that access doesn't like those '@'
so:
string sqlInsert = "INSERT INTO StudentmemberTable(Fname,Lname,Telephone,Email,Password) "
+ "Values(?,?,?,?,?);"
;
If you use the '?' you have to make sure you add the parameters to the connection in the right order since that is how they will be inserted.
