hey, here is my setup

i have a GENERAL table with medical patients basic information.
then i have multiple other tables (medications, visits, diagnosis, referring doctors), all linked by HistNum.

i have a form that opens a report filtered to a single patient and is going to display all of these tables. there is the main information on top, and then a subreport for the reffering doctor (this is all i have so far)

in the subreports properties, i have the Master/Child links set correctly by HistNum but nothing appears.. however, if i change it to ID, which is an irrelevant field in both tables, information does appear..

also, in an earlier thread where i ask about how to eliminate the whitespace left behind from cells of the table that are missing, i was told to "set the height of the controls to a negligible height and the can grow to yes", then the missing lines should be eliminated. for this, do all my fields i want displayed have to be part of 1 big text box, or multiple? (right now i use multiple)

what does this person mean by a negligible height?

heres a screenshot of the report

what does this person mean by a negligible height?

According to the Merriam-Webster Online Dictionary, negligible means:

so small or unimportant or of so little consequence as to warrant little or no attention

so it seemed obvious to me that setting a textbox to negligible height meant to set it to a very small height. The can grow property being set to yes will allow the textbox to grow to a readable height at runtime if there is something there. If there's nothing there, being set so small will mean that it's effectively not there, thus eliminating the white space.

ooh ok haha thanks a lot, i get it now.. i looked it up and tried it but messed up last time..

what about my master/child linking?
