formula from Excel to PDF

Hi Guys,

Im looking the code for the PDF file. In the excel in column H7 (over due) the formula is work. Now I need code also to fix in the PDF file.

see attached the sample (excel and pdf file).

here the details.
In excel, When select the status (pending) then select date in reservation date, then the over due display the no. of days.

please note:
the deposit field (Yes or No) as well as in the over due field and then the over due field would alert the user to see how many days the reservation is over due based on the deposit status (paid or not).

Please anyone can solve this in PDF file.

I may be wrong, but I fail to see how an excel forum will provide this solution. the calculation will be embedded in the form and the form will be created/edited in adobe acrobat? I think it can be done, as the logic is supported as a quick google shows. but this is not the place to get the answer. Unless the spreadsheet does something I am not aware of, its an excel forum.
