FormsCentral is discarding dropdown export values when importing PDF form

Question

I would like to disclose that I am fairly new to this process.
I have created a pdf from a word document. After creating the form portion in Adobe Acrobat XI Pro and adding in javascript validations and calculations, sourced mainly from these community forums I am encountering an error when importing the form to FormsCentral.  I have dropdown boxes that contain numbers (1,2,3, etc.) to select the amount of guests the recipient will invite. In turn, when selecting a certain number, the export value ($100,$200,$300, etc.) will show up in an adjacent text box stating in the amount it will cost.
This works fine in Acrobat, however when I import it I get a message:
     FormsCentral has successfully imported the PDF with the following exceptions:
     The choice field AddtD contains both display and export values. FormsCentral must discard the export values and this may cause existing calculations and validations to fail.
     The choice field AddtG&D contains both display and export values. FormsCentral must discard the export values and this may cause existing calculations and validations to fail.
When it comes to efficiency, I am aware I may be doing things the tedious way. But I would like some insight on how to make the textbox more active in this scenario. I will include my properties / validations and calculations:
Dropdown box 1 (AddtG&D): Export values, as previously discussed
Text box 1 (TotalAddtG&D):
Validation Script:
// null filed value if entry is zero
if(event.value == 0) event.value = "";
Custom Calculation Script:
// Set this field value to the value of the combo box
event.value = getField("AddtG&D").value;
The same goes for Dropdown box 2 and Text box 2, as they are identical. Any help would be great!

Answer 1

Well that simplifies it a lot, since all you need to do is multiply the field value by a constant amount in both cases. So the new calculation script could be:
event.value = 100 * getField("AddtG&D").value;
and for the other:
event.value = 45 * getField("AddtG&D").value;
though I'm not sure if that's the correct field name.
