Ok,
I actually found the variable i was looking for, it was :
{TRIGGER(Active,LastTrigger,File.Result.Name)}
incase anyone is looking.
however now i have another issue.
if more than one file shows up for a day (say they forgot to create a file one day so they create two the next) i can only the last file name from this variable, is there any way to get the jobs to only run for 1 file at a time and then repeat if more?
thanks again.
