Hi there,

Please, pelase help me if you can - I've exhausted every resource to try and solve what should be such a simple problem!

I have a table that has Date, SKU, UnitsBought, UnitsSold.

I have a report that groups the data on SKU and sums the UnitsBought and UnitsSold fields in the group footer.

I then have formula called {@Sellthru} that divides the total UnitsSold by the total UnitsBought.

I need the report to sort the SKU goups based on that calculated sellthu but that formula field is not available in the group sort expert.

I have been told that I can do this with SQL expressions but I have no idea how to do this - please can anyone suggest a solution - I have been trying to make this work for 3days now and I really don't seem to be making any progress - I urgently need your help!

Many many thanks in advance...
