Conditional INDEX MATCH

Hi All

Trying to solve a conditional issue with the attached spreadsheet.

Basically I have 2 sheets. The first an orders sheet which shows all orders from companies with the date of the order, whether it is a repeat order, and whether it has been delivered. The second sheet a customer account sheet which shows the order history by customer. I have used the following formula =IFERROR(INDEX(Orders!$B$2:$B$23,MATCH(0,INDEX(COUNTIF($A$1:A1,Orders!$B$2:$B$23),,),)),"") to extract the companies from the orders sheet however if a company has had no previous order (i.e. a new customer) and has not recieved a delivery yet I do not want him added to the sheet.

I have tried amending my formula in different ways but always encounter problems.

Any help would be great (and leave my day almost complete!)

Thanks
