How about this?

.ToolTipText = ("test"+dmy(date()))

>Thanks for the help Mike. So far no luck. The result I get is what is in the quotes - exactly This: ="Estimated next event date " + TRANSFORM(DMY(thenextdate))
>
> I pushed it around a bit, removing the transform and then the dmy byt the result was always what was in the outer quotes.
