Macro/Script for Automatically setting 2 Vport Views

[Spinxy]

marco is stopping after a user input. i have 2 view ports in one drawing, my macro unlocks all vports, then sets the first view then user input to select the correct viewport, then set the second view then user input to select the correct viewport, the script will then run on to save the drawing, saveas ...... then start over.
The problem is the command stops after i have selected the viewport saying invalid selection as below. dows anyone know how i can fix this!!
Command: -view
Enter an option [?/Delete/Orthographic/Restore/Save/sEttings/Window]: R
Enter view name to restore: "Sheet_1T"
Restoring Model space view.
Select Viewport for view: \
*Invalid selection*
Expects a point or Window/Last/Crossing/BOX/ALL/Fence/WPolygon/CPolygon/Group
Select Viewport for view:
Command:
here is the macro i'm using:

 
Tilemode
0
zoom
extents
-vports
L
OFF
_ALL
-view
R
"Sheet_1T"
\
_.PSPACE
-view
R
"Sheet_1B"
\ 
 
-vports
l
on
_all
_.pspace

another option could be to name the viewports somehow and include the viewport names into the script but i'm can't quiet think how i would do this!
any help would be great thanks
