I'm having a DTML problem here. I'm trying to test whether a subdirectory (whose id=ProjectID) exists under a LocalFS object.

<dtml-with ProjectID> <dtml-if "'&dtml-ProjectID;' in projectfiles.fileIds()"> The directory "<dtml-var ProjectID>" exists <dtml-else> "<dtml-var ProjectID>" does not exist </dtml-if> </dtml-with>

When I manually enter a value in place of ProjectID it works fine (ex. "'202006' in projectfiles.filesIds()"). When I use &dtml-ProjectID; it doesn't work. I presume that the value of ProjectID is not being translated into an appropriate format for the expression to work, but I don't know how to test this or to resolve this. Any thoughts? Better ways to do this?

Don't use the &dtml-xxx; within a dtml statement. The dtml code already knows about ProjectID, just use its name. Aslo, I don't see the purpose of the dtml-with statement. You would normally use that to establish a namespace after which you would not continue to use its. That does not appy here, as far as I can see. You could use the entity syntax in some of your other expressions, if you like. So it seems that this should do the job: <dtml-if "ProjectID in projectfiles.fileIds()"> The directory "&dtml-ProjectID;" exists <dtml-else> "&dtml-ProjectID;" does not exist </dtml-if> I'm assuming that ProjectID is some simple variable or property that is known to the document, which seems to be how you are using it. If it weren't known, the dtml-with expression would have given an error. Cheers, Tom P
