I'm also not sure the file path will be created properly as it doesn't pass the field values with the debugger.
var d = new Date();
var text1 = this.getField("NCMN");
var text2 = this.getField("CLASSLOT");
var text3 = this.getField("PO");
event.value = "/septaad1.org/shares/OPS_VehEng_Quality/NCMN/" + d.getFullYear() + "/NCMN_" + text1 + "_" + text2 + "_" + text3 + "_" + (d.getMonth() + 1) + "-" + d.getUTCDate() + "-" + (d.getFullYear().toString().substr(-2)) + ".pdf";
Thanks for the quick reply. I have read the article mentioned. I need two other issues with script answered:
Can the button be made to disappear after the initial saveas?
Please help with the conversion of field entries to text for use in the filename.
