runmlwin has encountered an error importing the model...

Hi
My do file stops dispite being done 'noisily'. This has happened 3 times out of 560 combinations of 3 age variables.

This is the main part of the do file:
gen fp1=age_yr
gen fp2=age_yr^2
gen fp3=age_yr^3
gen fpmh=age_yr^-0.5
gen fph=age_yr^0.5
gen fp0=log(age_yr)
gen fpm1=age_yr^-1
gen fpm2=age_yr^-2
gen fpm20=fpm2*fp0
gen fpm10=fpm1*fp0
gen fpmh0=fpmh*fp0
gen fp00=fp0*fp0
gen fph0=fph*fp0
gen fp10=fp1*fp0
gen fp20=fp2*fp0
gen fp30=fp3*fp0

}

This is the Stata message:

runmlwin has encountered an error importing the model results from MLwiN. Check that the model has run properly in MLwiN.

[fph0] not found
post: above message corresponds to expression 11, variable coef3
r(111);

These are the models which fail:
Model 115
fp2 =age_yr^2
fp3=age_yr^3
fph0= age_yr^0.5* log(age_yr)

Model 353
fph=age_yr^0.5
fpm1=age_yr^-1
fpm10= age_yr^-1* log(age_yr)

Model 504
fpm2=age_yr^-2
fp20= age_yr^2* log(age_yr)
fp30= age_yr^3* log(age_yr)

If I run these particular models in MLWin this is what I see:

I'd be grateful for any help.

Many thanks

You should be able carry on with the loop by either putting a capture in front of the post command so that it carries on with the loop when it fails, or by only calling post when runmlwin succeeds by putting it in an if !c(rc) statement.
