Does it have to be a calc field? Can you use the calc in a scripted process flow instead?
If you need to go with calcs: you can store the calcs in a table (one record = 1 version of the calc) and make sure only one calc is flagged as being the "active" one.
Then you real calc field can use the Evaluate function to read the content of the active record's calc field.
I wouldnt use a calculation. You can put all of your Z_Calc_3, Boot_Sole_Lenghts and the ISO standard in a table and lookup the ISO Standard through a relationship.
Thar's great, but how do actually check if C:\FileMakerUpdates contains a file, and then imports it, then deletes it after the import?
Thanks if anyone has any ideas
