Hi, I'm trying to put more than one calculation into a form field. Can I do that?
 
Basically:
field_A * 65 + 10% of field_B = answer in field_C
 
Hope that makes sense. Is it possible? Does anyone know the text I should use?
 
All I can get it to do is multiply by the 65 and give me a price in field_C. But I want it to add 10% of another field too.

Yes, but you will need to write a custom calculation script in Acrobat JavaScript.

but your formula looks like it calculates only one value from the value of 2 different fields and two constants.

You could use the simplified field notation for 'field_C':

(field_A * 65) + (0.10 * field_B)

Thank you, gkaiseril, the first part works very nicely on its own (field_A*65) takes the number in field_A and multiplies it by 65. But it doesn't seem to like the extra +(0.10*field_B)

(scratches head)

I've had another look at my field_C and it seems I was being very dim about how that was put together. I'd copied field_B along with its full sum (adding together seven other fields). I've now renamed it and asked it to include the final sum from field_B and not its calculation (iyswIm). Now your calculation works fine!

Thanks again.
