File move app part 2

[Bob Hartley]

Hi all.

I'm stuck.

I have created an app to move selective files based on their filetype and 
(sometimes) included text.
This code (below) lets you choose a directory, walk it and view a list. OK 
so far. Now on my second weekend learning revolution; I have linked a 
checkbox to a filter. :-) In my edited section I filter gHierList depending 
on whether one button is pressed. However, If I want to filter for two (eg 
jpg and gif) I double filter and end up with no selection.

I thought of creating a global eg gBobList and on each line create a local 
variable eg bobgif. Then would copy ghierlist into the local variable, 
filter the local and add to the final global (boblist). I need a global 
since another button will do something with this. In addition I want to 
view the list in the window.

Can anyone think of a simpler way?

cheers
Bob

code below

global gHierList
on mouseUp
   put empty into gHierList
   put empty into field 1
   answer folder "Pick a folder you want to walk:"
   if it is empty then exit mouseUp
   set lockCursor to true
   set cursor to watch
   directoryWalk it
-- I added this bit today
   if the hilite of button "JPEG" is true then filter gHierlist with "*.jpg"
   if the hilite of button "BIORAD" is true then filter gHierlist with 
"*raw*.pic"
   if the hilite of button "GIF" is true then filter gHierlist with "*.gif"
-- end of my edit
   sort gHierList
   put gHierList into field 1
   put number of lines of fld 1
   set lockCursor to false
end mouseUp

on directoryWalk whatFolder
   set the defaultFolder to whatFolder
   put the files into temp
   repeat for each line x in temp
     put whatFolder & "/" & x & return after gHierList
   end repeat
   put the folders into tDirList
   repeat with x =  2 to the number of lines of tDirList
     directoryWalk (whatFolder & "/" & (line x of tDirList))
   end repeat
end directoryWalk
