Hi Vitalikssssssss,
It worked, thank you for your help. I have one additional question:
From the first form, I pass the lineid to link to the next form. So far, so good.
From the first form, I also pass the brandid.
In the second form (which is based on the models table), I can then retrieve the brandid as a virtual field. My question is: is there a way to look up the brandname in the brands table? That would be a "nice to have", not strictly necessary to make the submission work.
In more general terms, I guess my question is: can I automatically look up a value based on a passed parameter in a table that is not in the table on which the DataPage is based?
