Hi!

I do not see the "^" sign in the date/time constant. When you do not provide it, VFP use current date settings to convert date constant into the date value. For some time your date settings where "YYYY/MM/DD". After settings changed to something else, you start to et empty date because error during convertin of constant to datetime value. The correct date constant format taht is not depended on the date settings is:

{^yyyy-mm-dd[,][hh[:mm[:ss]] [alp]]}

HTH.
