We are in the painful process of changing our file naming structure. I have a data card field for "Number" and that represents the part number/file name. I have several different serial number generators that are used based on product type. With this restructure, we are going to have each product type in their own folder. I would like to concatenate the "Number" field to be <folder name><serial number>. I do not know how to write the string to accomplish this.
