Stephen,
Without even checking, since it's the way it would be done in HC, just
use:
if tUsername is empty then ....
if tUsername exists then ...
You were already there. Didn't you check these out in the messagebox?

Really two questions:
How do I check if a variable is empty? Sort of like;
If !empty(tUsername)
// process here
Endif
Empty() is a Foxpro function that pops if what you are checking is
empty. I
can’t seem to find it’s equivalent in revolution. Am I approaching
this the
wrong way? And can I check fields the same way?
I suppose I could create an empty variable and just compare the 2?
But is
there an easier way?
Next question; checking the existence of a variable? Now I know I
can turn
on Strict Compilation (and I have) but I’d rather have the assurance
of
checking to see if a variable exist? Is this a non-issue in
Revolution?
Thanks
