Thank you for your post.
First, a description of "Extend Found Set". Perhaps you find a search of all people that have been inactive for the past year. Now, you want to include with that group of people those who have registered in the last month. In essence, you are extending the original found set to include another set of people. Therefore, "Extend Found Set" broadens the existing found set. Does that make sense?
Since these dates all occur in separate fields, it may be a bit difficult to show a listing, but it is possible.
First, you need to search the records for today's date in any of the 10 tabs. Assume the follow-up date fields in the ten tabs are titled, Date1, Date2, Date3, ... , Date10. Your script would look similar to:
Set Error Capture [On]
Enter Find Mode 
Set Field [ Date1 ; Get (CurrentDate) ]
Set Field [ Date2 ; Get (CurrentDate) ]
Set Field [ Date3 ; Get (CurrentDate) ]
Set Field [ Date4 ; Get (CurrentDate) ]
Set Field [ Date5 ; Get (CurrentDate) ]
Set Field [ Date6 ; Get (CurrentDate) ]
Set Field [ Date7 ; Get (CurrentDate) ]
Set Field [ Date8 ; Get (CurrentDate) ]
Set Field [ Date9 ; Get (CurrentDate) ]
Set Field [ Date10 ; Get (CurrentDate) ]
Perform Find 
If [ Get (FoundCount) = 0 ]
Show Custom Dialog [ "No records found" ]
At this point, you have your set of records that need calling today. Now the trick is to find the caller with the correct tab. Once found, you want to display a list of names, so the name needs to be put into another field. Create a new text field "DisplayName".
Assume the contact names in each of the tabs is titled Name1, Name2, Name3, ..., Name10. Extend the above script as follows:
Go to Record/Request/Page [ First ]
Set Field [ DisplayName ; Case ( Date1 = Get (CurrentDate) ; Name1 ; Date2 = Get (CurrentDate) ; Name2 ; <continue on...> ; Date10 = Get (CurrentDate) ; Name 10; "" ) ]
Go to Record/Request/Page [ Next ; Exit after last ]
Go to Layout [ <Layout that includes DisplayName, Company and Phone number> ]
This should get you pointed in the right direction. Let me know if you need clarification for any of the above steps.
You are going to continue hitting the same exact issue over and over. Like I said in your last post, you need to fix your structure by using a related table...

We would be negligent in our responsibilities (and ethics) as Developers if we did not HIGHLY encourage you to change your data structure now, while it is still in the early stages. Mr. Vodka is absolutely right. And you can see by the script provided (having to search through multiple date fields) how tedious it can be when, if these dates are RECORDS in a related table, your script would change to be simply:
Enter Find Mode [ ]
Set Field [ yourDateField ; Get ( CurrentDate ) ]
Set Error Capture [ On ]
Perform Find [ ]
You see how easy it could be? :smileyhappy:
Honestly I would change it but the data is already being used live on IWP and this is actually the final product of the database I am just adding stuff to it. I was going to use a relational database in the beginning and was trying to but then I couldnt figure out how to do this. I am just getting into my MIS courses at school right now and am learning new things everyday from my work which is what I'm doing this database for. Is there any good articles on relational databases that you guys know of?
