Archive Script 0.0.0 for Nuke

Hi Throb , ed I copied the archivescript to my plugins folder. getting this message dirname: Unknown command while executing "dirname [filename $n]" ("foreach" body line 3) invoked from within "foreach n [nodes] { if {[class $n]=="Read"} { set readdir [dirname [filename $n]] set dirtomak..." invoked from within "if ![file exists $destpath] { error "Path does not exist :\n$destpath" } else { puts "\n---Archiving Script : [value root...." invoked from within "if [catch { panel "Script Archiver" { {"Destination Path" destpath f2} {"First frame for archive" framerangefirst} {"Last frame for archiv..." (procedure "archivescript" line 8) invoked from within "archivescript" just wondering if the scripts works for MAC? Cheers
