Check that.  I am having problems creating a search FORM, not QUERY.

Search Form 2.0

My employer provides me with a 32-bit version of Access.  Search Form 2.0 requires 64-bit Access to run.  I've inquired about an upgraded version of Access, but I'm not optimistic about my chances.  Are there any videos that cover form queries with combo boxes as search criteria?  I have not found any (yet).

Tom -
Did you try building it?  I just glanced through the code and I'm not seeing anything in there that would not work in 32 bit Access.
Yeah upgrading EVERYONE to 64bit would be the best solution.  But as long as everyone is using either 32 or 64 you should be fine.
Where you run into issues is when you start mixing it up between people.
You don't want to upgrade to 64 unless everyone else is also upgraded.

Most of the stuff here will work just fine in 32bit. Especially the older classes and videos.
Some of the very latest MAY not work but until you get into some pretty heavy programing you should be just fine.

BTW - I don't know how many people your employer has but upgrading really isn't that big of a deal either.
It does take some time though.  You uninstall Office, then have to re-install Office and choose the 64 bit install. That's it.
All of your .docx and .xlsx files will open just fine.  You won't loose data.
I fought it for a long time but when I started upgrading computers because they got way old or died I just made the jump and it wasn't nearly as bad as I thought it would be.

Just a quick addition.  I don't think that your issues are with the bitness of Office.
More likely it is something you are missing in getting the comboboxes to "play nice" together.

Just like the teacher said in elementary school (for me at least),  "Show us your work" applies here.
We can guess all day long but if we see what you are doing the guys here can offer better advice.
