>>>OK, I'm sending you a "salary.exe" which is a self extracting zip file. Run it from anywhere and extract to a folder of your choice. I've included a .prg which will create an .fxp when it's run. So I've used both report variable and a simple program to solve your problem.

>I'm really indebted to Lisa Slater (who is in New Zealand these days) for teaching me about the report writer. She wrote an excellent booklet some years ago called "The Foxpro 2 Report Writer". It was available from Pinnacle publishing. And might still be around. Lisa's a programming genius.

David, have you read the Dragan's reply?
It seems that it is possible to do it using 3 report variables.
Vars are calculated in the order as they apper in the variable list.

The trick is that second variable expression uses inside iif()
the value of third variable. This allows to sum previous group when
in the next group header !
This work faster since calling udf from reports is slow.
What do you think about this?

I tried to use Lisa's coolbutton class but without success.
She wastes her time for application generator as I read from her
article in the ms vfp site.
