I'm sorry. I posted this in the "Report" section. After looking through the questions, though, I wasn't sure if that was the appropriate place for my message about errors. Now...
First of all, I am an extreme novice (have only been trying this for a little over a week). I have created a form for work orders. The work orders contain 2 tabbed subforms, one for Labor and one for Parts Used.On each subform, I have an "Extended Price" field that calculates the total for each Part used and the total for Labor for each task. Then, in the footer of each subform, I have a formula that sums the ExtendedPrice fields. In the form, I reference back to the SumExtendedPrice for each subform, and then, total the two. To return a 0 on null fields, I use the Nz function on the Form's references to the fields. This is successful (seemingly so) on the form. When I click the button I set up to take me to each Work Order's invoice, I have a "SIZE#" error in the report's references to null Labor or Part totals. On the form, this is not so; it only does this on the report. However, when I do a "Print Preview," the field will read $0.00, and it will total. Why, oh, why does it do this? Help me, please! Thank you!
