Joe,

The '.' (dot) marks the end of macro substitution. Try

loPrevDay = EVAL("this.parent.parent." + this.parent.parent.priorday)

>I'm working on a calendar class in vfp7. It's a container with child containers that act as days. User click a day container to insert an event. If they click a different day after one has been clicked already the event is moved. So I needed a way to reference the prior day clicked. I did this by storing the control name clicked in a property called "priorday" on the calendar class.
>
>this.parent.parent.priorday would be set to "Day4" for example. Now when I want to reference the prior day when control "Day5" was clicked I could do something like this.parent.parent.&this.parent.parent.priorday..eventhours.
>However this doesn't work and I'm not sure why. Any tips?
