The users for the database I am making are not computer literate so i am trying to make it as easy as possible
It will be a simple AND type find, which is normally ok.
If they try and enter more than one field in you example they all have to match. For Example...
Customer will be Smi AND they also enter
PO# will be 76644 then both of those field will have to be TRUE to find a record.
Please note that mulitple records could be found also.
Here is a thread with quite a few scripted find examples: Scripted Find Examples
They all use data entered into global fields to enter search criteria into find requests. Your "search form" can be a collection of such global fields. You can pop up a modal window with these fields on in, change to a layout with these fields or you can put the global fields on the same layout where you want to see the results. The basic script used is the same.
I've included a screen shot of such a modal window that I use for setting up reports.
