Split Form Behaviours with Subform

By the way, I can copy that post here from the email notification, but it will be in a bit. I'm on an iPad right now and copy/pasting is harder.

Oh, that'd be fantastic. Thanks so much :)

EDIT: removed lengthy code addition. Included in code tags in post below.

That's the one! Thanks!

Sorry for the delay. I think I've managed to make BuildFilter work properly again using your debugging techniques. strWhere wasn't being constructed properly and was feeding nonsense to .FindFirst through BuildFilter.

I'm still encountering issues with the Form_Current() code for subMain. Here's what it's doing:

- When I open the form, I get runtime error 3077: Syntax error(missing operator) in expression. The Debug button takes me to "rst.FindFirst BuildFilter2"
- I reset the code and let frmEdit open, place a breakpoint at the beginning of the code in the subMain module put a date in my txtStartDateBefore field, and start stepping through the code.
- There are no issues when I get to "rst.FindFirst Buildfilter2"; the Immediate Window displays "[StartDate] <= #12/31/2011#" which is the date I picked with the date picker. I can successfully step through the rest of the code without any errors... Strange...
- But my bound controls still don't change the record displayed when I click on different records/fields in the subform, and clicking the First/Previous/Next/Last buttons (which I created to change the displayed record in the bound controls) doesn't change anything in the subform, either.

So the code seems to run successfully, but is not performing as I want/expect it to. And then there's the issue of the error on Load...

I really feel the need to thank you guys for all this help and guidance you've been providing. I know you don't have to do this, and I know that spoon feeding can be frustrating. So thank you both, so much, again.

'frmEdit has txt, cmb, and chk controls, as well as an option group with 2 radio buttons on it.
'The combo boxes are meant to allow the user to choose how their results are filtered, so
'users can select "begins with," "ends with," "contains," "is bewteen," etc. for many of the
'text box controls.

'I've abridged and edited the code, but it's still a rather lengthy. The sections for First Name,
'Last Name, and Sponsor are mostly identical to the Project ID section, so I cut them out 
'except for a reference to their location.

WOAH!

So I took a bit of a hiatus on this, finding a workable alternative involving a textbox whose input would allow the user to navigate directly to whatever record they wanted.

But I've made some progress! Turns out my big problem was that the original datatable (which, in my defense, I didn't create), didn't have a primary key. So I created one, and lo and behold my form started (almost) working!

What's happening now is that, while the main form and subform do reflect each other's behaviours, my subform is only displaying one record at a time. Obviously, I would like it to display all the records that meet the user's search criteria and highlight rather than isolate the current record.

Haven't done much troubleshooting, yet, but I thought I'd post the update :)

PS: I'm going to repost some of the more pertinent info in a new thread, since this one's getting rather dated. Find it here: http://www.access-programmers.co.uk/forums/showthread.php?p=1265126#post1265126
