How to make function: line amount total and final colum total at the bottom (Acrobat pro 9)?

Question

The form is like this:
col 1
col 2
col 3
col 4
col 5
Row 1
amount
amount
amount
line total
Row 2
amount
amount
amount
line total
Row 3
amount
amount
amount
line total
Row 4
amount
amount
amount
line total
Row 5
colum total
colum total
colum total
colum total
The problem is that even though the calculation seems to be right, the final total, colum totals and some of the line totals don't update. The sum remains zero.
Could there be a wrong tab order? Could somebody tell me the right order? I've tried several variations, but I just can't get it work . Could somebody help me please?
Thanks in advance!

Answer 1

It's most likely an incorrect field calculation order, which is not at all related to the tab order. In case you don't know how to set it, select "Forms > Add or Edit Fields" to go into form editing mode, and then select "Forms > Edit > Set Field Calculation Order".
Arrange the order so it makes sense, which looks like it should be:
col 2 total
col 3 total
col 4 total
Row 1 total
Row 2 total
Row 3 total
Row 4 total
Row 5 total
Other arrangements might be just a correct, but it's important that the row totals are in that order. You should also check it again when you have the form ready to distribute to make sure it hasn't changed as you've done further editing.
