How to pass variables to shell script?

Question

I have a shell script which uses the touch command to change the date of a file.  To run the command on the command line the syntax is:
set-file-date.sh <file> <date>
I'm trying to run it from an automator workflow, so I'm prompted for the date, then the workflow iterates over the finder items, i.e., files, and changes the date of each files.
The problem is in the "Run Shell Script" action.  The $@ is substituted with the file names selected in finder, so this will echo the file names:
for i in "$@"; do
     echo "$i"
done
What I want to do is something like this:
for i in "$@"; do
     set-file-date.sh <DATE VARIABLE> "$i"
done
But I can't prompt for the date value, and pass it to the script.  I've tried using the "Get Value of Variable" and the "Ask For Text" actions.  I can either get the file names from finder OR the text input in the "Ask for Text" action, but not both.
Is what I'm trying to do possible with a shell script?
-Thanks

This is standard AppleScript text concatenation...
set howManyWords to do shell script "wc -w /path/to/file | awk '{print $1}'"
do shell script "/usr/local/bin/growlnotify -t 'Corpus' -m '" & howManyWords & " words were added to the corpus.'"
in other words, just use the & to concatenate the parts of your text together.
