INPUT() vs Auto selecting on single record found

[Tom_Stevens]

I have 3 tables

- TRACKING NUMBERS (a basic list of key ID's that I use to link all parts of a project)

- PURCHASE LOG (a place for a company purchaser or shipper receiver to log purchases - Using the Tracking numbers as a P.O. number)

- TIME LOG (a place for field technicians to log time to a tracking number, and also select which purchases they have used on a job) 

A field technician makes a time log entry to a specific tracking number. The time log pulls up all purchases for the tracking number in an inline view.

I have 2 actions set up.

1. The red "X" - Both shows unclaimed purchases for the job, & if you tap it when its grey it clears a claim on a purchase.

2. The green "✓" - Both shows a claimed purchase for the job, & if you tap it when its grey it claims a purchase.

Currently when you tap on the  "✓" it pulls up the INPUT() window and makes you pick from all of your time inputs related to the tracking number.  I was wondering if it was possible in the action via a formula to have the action search the REF table and if it only finds 1 possible value to return that value, else ask for user INPUT(). 

I have attempted to add an IF() to the claim purchase action with no success as follows: 

IF(

COUNT(
SELECT(TIME LOG[KEY ID],
AND(
[TRACKING NUMBER KEY ID] = [_THISROW].[TRACKING NUMBER KEY ID],
[REPORTED BY] = USEREMAIL(),
[DATE] = TODAY()
),FALSE)

)>1, INPUT("PICK TIME LOG:",[TIME LOG KEY ID]),

ANY(
SELECT(TIME LOG[KEY ID],

AND(
[TRACKING NUMBER KEY ID] = [_THISROW].[TRACKING NUMBER KEY ID],
[REPORTED BY] = USEREMAIL(),
[DATE] = TODAY()
),FALSE
)
)

)

Is it just not possible or is my formula logic out to lunch?
