thank you so much markus! that was it! you sir, are most excellent! have a wonderful week!...

this is probably a total newbie question, but i can seem to figure it out.
when i run this code it gives me this error:
Undefined index: work in FILENAME on line 3... which is the file-to-be-uploaded name.

i copied this from php.net, so i thought it should work. then i copied the simpler code from w3 schools, and that gave me the same error. but, here is my html and php:

[HTML]<form action="process .php"...
