st: Stata programming and the scalar/tempname command

["Anna-Lisa Pierre" <annaf2001@hotmail.com>]

Hi this is a bit of a programme that I am writing. Can anyone spot why it 
does not work? The scalar commands do not appear to work. I get the 
following error "= invalid name" and "unrecognized command:  scalar__0000OP" 
when I run the programme. Any help is greatly appreciated.

 tempname catnum degreef obs
 tempvar scoreqq scor_uqq scor_nqq diffqq1

 noisily oprobit `*' `if' [`weight'`exp']

 scalar `catnum'=e(k_cat)
 scalar`degreef'=e(df_m)
 scalar `obs' = e(N)

 predict `scoreqq' `if', xb
 ge `scor_uqq' = `scoreqq'
 replace `scor_uqq' =. if `1'==.
 ge `scor_nqq' = `scor_uqq'
 replace `scor_nqq' = `scor_uqq' - _b[`2'] if `2'==1
 replace `scor_uqq' = `scor_nqq' + _b[`2'] if `2'==0

 ge `diffqq1' = normprob(_b[_cut1]-`scor_uqq') -   
normprob(_b[_cut1]-`scor_nqq')  if `1'~=.
