I could not get it to work. Here is what i did. At the top I put the following line,
put field "Folder" into whatFolder at the bottom I tried both of these lines and nothing was put in the field put tDirsToDo into field "list" put tDirList into field “list” then I tried this line put "tDirList" into field “list” and it put the word tDirList in the vld as would be expected. This was accessing a folder with no sub folders and only a few hundred files. All of the other file Lister even the recursive had no problems with this folder. What am I supposed to be putting in the field?
