Error version 5.5

[Hendrik]

Hey!

I´m using Zeos 5.5 with Firebird and Delphi 3.

When I try to set a ZZIbSqlQuery into the edit-Mode or to do any changes with the table, the following error happens:

Connection is not defined
Dynamic SQL Error
SQL error code = -104
Token unknown - line 1, column 14
"Tablename"
Invalid Token'.

Has anyone an idea what i´ve done wrong?
