Nested IF checking non blank cells

[brentandrews]

Hello,

I want to create a nested IF formula that checks for blanks in three cells.

If A1=Not blank, then enter in "Live"
else
If B1=Not blank, then enter "Signed"
else
If C1=Not blank, then enter "Interested"
else
enter blank into cell

I've been playing around with formulas, but can't seem to get it to work. Any help would appreciated!

Thanks
