calculation with a dataset which don’t exist

[Anonym]

Hello,

I would like to make a fpscript formula with the following behaviour :

– if a dataset called “A” (for instance a dataseries of 10 values) exists in the rootfolder, then return the product 2 x A

– else, return the value 0

At the moment my fpscript formulas return errors if they try to make calculations with dataset wich don’t exist.

Is it necessary to use exceptions ?

Thanks in advance

There is a FPScript [b]Try[/b] … [b]Catch[/b] statement. But you cannot use it in this case.
Create a dummy FPScript formula ‘A’ which returns 0.
