Sentential Validity -- Logic

Hi everyone,
I would like to know if there is any difference between sentential validity and validity of an argument?
In my head, all sententially valid arguments = valid arguments
but I'm not sure if it is the case vice versa :s-smilie:
Please help ~~

Doesn't "sentential validity" just mean "validity in a sentential argument"? If so, then it follows that all (valid) sentential arguments are (valid) arguments, but not all (valid) arguments are (valid) sentential arguments.
