First time scripting, ever. . . Help with Automator and Sed

[czucker]

So, please go easy on me.

I'm trying to write an automator action to resize a postscript file.

So far it is set up in automator as follow:


It's working well enough, except for the "$1" variable in sed. Instead of getting the value of the variable, the literal $1 is being inserted into the postscript file.

I know it's probably something obvious that I'd know if I had any clue what I was doing. . . But, I'm trying.

Any help would be appreciated.

Thanks,
Chris
