Passing variables into a new session

Hello,

I am trying to include a small routine to add some text to an order when a certain screen is reached in our Mobile application.  Here is what I have to get out of the screen and into a script:

        Enter "/oiw32"  process=iwxx_print_status.txt" 

          using iwxx_order_num = "&F[Order Number]"

          using iwxx_stat_src = "ENRT"

This successfully opens the new session, but the script itself does not run, although the trace shows that it has started.  Instead, I just see the SAPLCOIH.e0101 script in InputAssistant, which is the first screen when you execute iw32.  Here is the inputscript:

parameter iwxx_stat_src

parameter iwxx_order_num

set V[iwxx_stat_src] "&U[iwxx_stat_src]"

set V[iwxx_order_num] "&U[iwxx_order_num]"

if V[iwxx_stat_src=ENRT]

  set V[iwxx_comment] "Work Order set to En-Route"

endif

//Screen SAPMZMOBAM.0100

//  Enter "/oiw32"

Screen SAPLCOIH.0101

  Set F[Order] "&V[iwxx_order_num]"

  Enter

Screen SAPLCOIH.3000

  Set V[z_iw32_comment_date] "&V[today_user] - &V[today_h:m] - &V[_user] : &V[iwxx_comment] "

  copytext fromstring="z_iw32_comment_date" totext="tmp"

  copytext fromtext="tmp" toscreen="X[LTEXT]"     "-appendline"

  Enter "/11"  // Save

// Change Order: Initial Screen

Screen SAPLCOIH.0101

  Enter "/15"

// SAP Easy Access  -  User menu for Richard Haynes

Screen SAPLSMTR_NAVIGATION.0100

  Enter "/15"

Any suggestions as to how to get the inputscript to execute instead of just going to the screen would be appreciated!
