Do you have a screenshot of the output?

I can show it to you without the IIF statement.  I cant do anything when the IFF statement is in there

It looks like you have a space in the field name 'Is Taxable'.

Did you get an error parameter when you run it?

Hi Sami,  I double checked and there isnt a space.  Just to besure I retyped it in.  When I click the RUN button nothing happens.  If I choose to view the DataSheet View nothing happens.  If I close the query and then double click to open it, I see the hourglass very briefly then nothing happens.  I dont get any error messages.  I thought if I looked at the SQL I might see what the issue is but it looks okay to my totally NOT expert eyes.  Here is the SQL statement as an image.  does it mean anything that there is a number 3?

Go through the.Troubleshooter

Try this just to eliminate possibilities.
Create two queries. The first one has only the extended price. The second one does what this one is doing.

Hi Sami, I did the 2 separate queries  you requested and the one with the IIF statement still didnt work.  I saw at the bottom right corner of my laptop that there were updates to be installed and thought... hmmm... I wonder if that is the issue and not the IIF statement at all...So I shut everything down, did the updates... and everything works just as it should... GAH!!!  I guess it was the equivalent of pulling a Nintendo cartridge out... blowing on it... and putting it back in and now it plays just fine...  Adding restart the computer to my list of things to try before bothering everyone...  Thank you to you and to Alex for trying to help me with my issue.. I really do appreciate it!

Shallena You are most welcome.

Going through the troubleshooter I pointed you to earlier is very helpful. Check for updates and reboot your computer is one of them.

I spent most of my day trying to recover from a bad update three weeks ago. I finally managed to get it working after about six hours.

Same thing - connection to my SQL Server from my computer didn't work, however it works fine from my laptop. Both of them are pointing to the same database hosted on a dedicated server on the web.
