Unknown file error: /Users/bruce/webx 21 (Is a directory)

Question:

I am seeing this error in my webx.log file.

Answer:

You have a macro that is attempting to use the fileWrite WCTL command, but is using an empty file name. This error is returned by the file system of your OS.

Example:

%% "".fileWrite ("scoobydoo") %%

or

%% name.fileWrite(data) %%

where the variable "name" is blank or does not exist.
