From VFP help:
LOOKUP(ReturnField, eSearchExpression, SearchedField, cTagName)
I cannot understand the meaning of third parameter, if fourth
parameter is present.
If I specify cTagname, eSearchExpression is searched using tag cTagname
and there is no any need to use SearchedField.
What in this case I must put to SearchedField ?
If I leave SearchedField empty, error occurs. Is this an illegal
VFP design ?
