Uknown System Variable (@DTL_TAXTTL)

[Milos MNE]

Hi,

I'm trying to get the tax amount from every check item and I've found in SIM manual that system variable for that is @DTL_TAXTTL but when I try using it I keep getting this message:

The code I'm trying to test it is:

event inq:1
var i:n5
var count:n5 = 1

if @numdtlt = 0
exitcontinue
endif

window 10, 50

for i = 1 to @numdtlt
display count, 1, "Detail ", @dtl_type
count = count + 1
endfor
waitforclear
endevent

Can anyone help me?

Regards,
Miloš.
