I wonder if the OP's problem could be caused by this, excerpt from OOo Calc help: " Iterative references In this section you can delimit the number of approximation steps carried out during iterative calculations. In addition, you can specify the degree of precision of the answer. Iterations Specifies whether formulas with iterative references (formulas that are continuously repeated until the problem is solved) are calculated after a specific number of repetitions. If the Iterations box is not marked, an iterative reference in the table will cause an error message. " Note the last sentence.
