Can you provide or link a FULL documentation?
There is limited documentation in HELP under Process Number Variable Calculations. If you are obtaining erroneous calculations via FFCore please author a SPAR.
I'm also interested. I have seen screenshots where calculations like this have been set in the fields directly. Example:
Not working: $FFvar1$+2*$FFvar2$ (but syntax is correct, otherwise FFC throws an error)
Working fine: $FFvar1$+$FFvar2$+$FFvar2$
This workaround works for me at the moment but is harder to read and limited.
WHERE can I find a documentation about calculation?
Here's the screenshot from a Xerox presentation:
I do not believe that a formula can be used directly in the external node parameter field.
My idea is to add to the MAX setup for a hotfolder two custom number fields (e.g., divisor and substractor -- the FFCore variables will be $FFdivisor$ and $FFsubtractor$). The MAX csv file will need values for the fields.
On the External node parameter settings add "$FFdivisor$" and "$FFsubtractor$", use these values within the external node script file to compute the value you want.
Does it mean the variable calculation must go through MAX but not put the formular directly in the parameters field of the external node?
One could add addition variables (e.g., $FFsubtractionnumber$ and $FFdivisor$) via MAX. These variables then could be fed to the external node via parameters. The computation could be completed in the external node.
As I knew number variable can be calculated in FF Core 18.104.22.168, I have a pdf containing 16 pages which will be printed duplex on the printer, the first 14 pages are letters need to be mailed to our clients, the last 2 pages are mailing instructions for our mail team, that said there will be 7 mail pieces (16-2)/2. I put the formular ($FFwfdoc.pages$-2)/2 in the parameter area of the external node where I expect the sent out email to show "Mail piece: 7" but instead it shows "Mail piece: (16-2)/2", how can I perform calculation in this situation?
