Argument Not Optional

[gilly]

What does this error mean??
"Argument not optional".....im trying to call a sub procedure from ASP to my vb module ie:

call obj.sb_InsertStandardJourney(cstr(strjourneyfrom),cstr(strjourneyto),cstr(standardmiles))

[Jimbob]

it thinks you are not supplying all of the arguments requierd by the sub

how many arguments does the sub need - you seem to have supplied it with three??
