Hello macropod,

Thank you for your answer and tutorial. I'm interested in what you are suggesting, but I'm not sure what you mean by 'test the dropdown formfield's state and vary the output accordingly'.
I created a yes/no dropdown and then went to the Word Field Maths Tutorial you suggested and used a formula in there, =IF(DEFINE=YES, $0.00, D11*0.0835) but it didn't work. I didn't know what you were referring to in your Maths Tutorial that I should use so I just guessed it was the DEFINE function. I don't know if you were referring to the macro in there or not either. Can you be more specific re: what a formula would look like or what the macro would look like? I'm not too knowlegdable and need a little more help if you can.

Thank you, derby46a
