Scale Photoshop layer using AppleScript

Obviously, this is a Mac PS issue.

I am trying to script scaling a Photoshop layer (a smart object layer) to a specified percentage that I calculate from a layout in InDesign.

However, I am stumped on the syntax I should use to actually get the layer to resize, or perhaps I don't know how to call out the layer properly.

Here is my code (it is very simple at this point in time:

tell application "Adobe InDesign CS6"
          set mySelect to selection
  --error trap to make sure I have graphic content selected
  
          tell active spread of active window
                    set thisBox to item 1 of mySelect
                    set HScale to the absolute horizontal scale of thisBox
  
          end tell
end tell
myScaleConversion(HScale)
set PSScaled to result as real
tell application "Adobe Photoshop CS6"
          set thisLayer to current layer of current document
          set scaleSet to {horizontal scale:PSScaled, vertical scale:PSScaled, anchor:"top left"}
  scale current layer of current document with scaleSet
  
end tell
on myScaleConversion(HScale)
          set ScaleRatio to 2.5 as real
          set PSScale to (ScaleRatio * HScale)
          return PSScale
  
end myScaleConversion

I would appreciate any help with this. I run this script and no error messages occur, but then again, nothing happens to the Photoshop layer I have targeted.
