im using a script to move my xtray instead of show/hide

the tray is on the right side of the screen and should normally be past my screen res using

  xTrayX  $ResolutionX+171$

this is so itll move in from the right side to show itself and then back to the right
what i need is for it to pull the tray width from my var file using

  xTrayX  %#ResolutionX+xTrayCurrentWidth#%

with the same script to move it in from screen the top one will work as i need unless another icon is added to the tray then it doesnt move far enough since its a fixed number, if i use the second line it causes the tray to move across the screen from the left to right side to the spot needed.

EXAMPLE:
IF trayOn
  xTrayX  $ResolutionX$
ELSE
  xTrayX  $ResolutionX+171$
;  xTrayX  %#ResolutionX+xTrayCurrentWidth#%
ENDIF
xTrayY  -128
xTrayAutoSize  25 5
xTrayBorders  8 23 12 102
xTrayXSpacing  4
xTrayDirection  ".left"

THIS IS THE SCRIPT:
  *Script exec  !xTrayReposition %#ResolutionX-xTrayCurrentWidth%# -128 %#xTrayCurrentWidth%# 128 25 4

PLS HELP GUYS. THIS IS DRIVING ME INSANE.
