Best way to validate currency field based on two picklists

Question

Hi,
Im having a great deal of trouble creating validation for the following statement:
If (Task type =”Call” or “Callback”) and (‘Outcome Category’ is “In Progress” or “Tried and Failed to Save” or “Saved”) then (‘Total Value of Policy’ must be > 0)
Both task type and outcome category are picklist items.
What is the easiest way for me to do this? Ive created something horribly complex which only works when I first create the record (possibly because of the use of FieldValue rather than stored values). Ive seen people use the NOT function before to do this - could this be an option?! Ive had no luck with anything Ive tried so far.
My current expression is as follows:
(FieldValue('<cTotal_Value_of_Policy_ITAG>') > 0
AND FieldValue('<Type>') <> LookupValue("TODO_TYPE", "Investigation") - - Because call or callback are the only other options in the list.
AND (FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "In progress")
OR FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Tried & failed to save")
OR FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Saved")))
OR FieldValue('<Type>') = LookupValue("TODO_TYPE", "Investigation")
OR (FieldValue('<Type>') = LookupValue("TODO_TYPE", "Call")
AND (FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "In progress")
AND FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Tried & failed to save")
AND FieldValue('<IndexedPick2>') <> LookupValue("OCC_INDEX_CUST_LOV_EVT_ACT_2", "Saved")))
Sorry for including this confusing chunk of code, but I think it explains how more complex i have made this than i probably need to!!
Any help would be greatly appreciated as this is quite an urgent issue..
Many Thanks

Anon,
In your edit form, create two hidden items p10_ha, p10_hb (for e.g.) Make the default values for these items as values of p10_item_a and p10_item_b respectively. So when you are processing the update, you have old values in hidden items and new values in p10_item_a and b.
Now create 'after submit' pl/sql computation and put similar code
if p10_ha !=1 and p10_hb !=1 then
    if p10_item_a = 1 and p10_item_b = 1 then
    -- your business logic here   
   :p_date_item := sysdate;
   end if;
end if;Hope it helps
Cheers
Hari
