- Order Entry System
- Order Form and Details Subform

- IIF Function (If/Then/Else)
- Proper Rounding of Values
- Bankers Rounding

Why would you calculate the sales tax on each line?  Shouldn't the sales tax be calculated on the sum of the extended price of all taxable items?

It's the same either way. (1+2+3+4)*10% is the same as (1*10%)+(2*10%)+(3*10%)+(4*10%). My way is easier.

If it's a single field you can use a DLOOKUP.
If you have 2 prices in the product table, purchase and selling you could just add both to the query and show both.

I cant enter enter new records in my order detail query
SELECT OrderDetailT.OrderDetailID, ProductT.ProductName, ProductT.ProductPrice, OrderDetailT.Quantity, [ProductPrice]*[Quantity] AS PriceExTax, IIf([IsTaxble],Round([PriceExTax]*0.2,2),0) AS TaxPrice, [PriceExTax]+[TaxPrice] AS PriceInclTax Read More...

Not surprised. A lot of the time when you create a query with a JOIN it becomes non-updateable. Use a form with a subform.

how can I make it editable?
