There's a very simple way of doing it. Set the price field as read-only
(don't forget to set the default value so it doesn't clear when the form is
reset), and then go to the Properties of the total field, Calculate tab,
and select the first option: Value is the (product) of... Then select the
price and quantity fields in the list, and you're done.
I have tried to do that simple thing but for some mysterious reason I
cannot simply select the items I want to multiply. I can SELECT ALL. and
sometimes get a random item to select, but cannot simply select the items I
want to multiply - as they show in the tutorials. What am I doing wrong? Do
I have some odd command set improperly somewhere else in the form?
Are you clicking the tick-boxes next to the field names?
Yes - and nothing happens - well almost nothing... If I go along the list of field names and try to click in the boxes - every once in awhile one will actually set a check... But it doesn't work on ones that I WANT to work... If I deselect and try to select again it won't work - then some other box will work.... it's the weirdest thing. I tried downloading a copy of Acrobat XI because I figured there had to be a bug in the copy I had. And the same thing is happening!! I am at a loss. That's why I was resorting to the idea of writing a simple java script to get it to do what I need.
Very odd.. Use the Simple Notation option, and just enter:
quantity * price
I will be putting a field in for the "quantity" part, but had thought that I could avoid doing the same with Price. Can I put "quantity*6" for quantity times $6 or $12 or whatever it is? Does it automatically enter it in the total section?
I just tried "quantity*6" and it worked! Thanks...
user the spacebar to select and unselect. I was also having this problem, and just discovered this work around!!
