	"invoice amount' is simply multiplying two Darabase fields, as in: {InvoiceLines.Quantity} * {InvoiceLines.UnitPrice} so we have in the group footer, "sum of @invoiceamount(number)" field I was hoping I could simply use that summary field, in my chargeback amount formula ;( Rich

	you cant really do conditional summary the wa you have it if datediff('m',startdate,caceldate) in 3 to 7... you can instead apply the condition to the formula and sum that formula if datediff('m',{servicessetup.startdate},{{servicessetup.caceldate}) in 3 to 7 then (({InvoiceLines.Quantity} * {InvoiceLines.UnitPrice}) *(.75)) else 0 now sum this at the client footer
