hye! i'm new in Oracle Professional Development.. I'm creating an on demand software. I have 3 text boxes on my form
1st text box will carry Product's Actual Price
2nd text Box will carry Product's Selling Price
3rd text Box will carry Profit..

3rd one is display item..this will carry "selling price - actual price" and then result into 3rd box.. that would be profit..

my query is
select nvl(:PL_PRODUCT_SELL_PRICE, 0) - nvl(:PL_PRODUCT_ACT_PRICE, 0) INTO :PL_PRODUCT_PROFIT FROM SBM_PRODUCT_LIST;

Now, please help me how can I move Proceed? I've currently applied this trigger as POST-query on form and POST-CHANGE on :PL_PRODUCT_PROFIT

PLease help me as soon as possible. I've to proceed..
I'll be very thankful to you professionals.

1) Can you please read and follow the orafaq forum guide - especially the part on how to format your post.
2) Since you don't need to query the DB to get this information you shouldn't be using a select statement. Instead you should be using a direct assignment:

:PL_PRODUCT_PROFIT := nvl(:PL_PRODUCT_SELL_PRICE, 0) - nvl(:PL_PRODUCT_ACT_PRICE, 0);

3) You should get into the habit of always prefixing item names with the corresponding datablock.
4) You should use when-validate-item instead of post-change.
