Trouble with Concatenate

[cadamhill]

=CONCATENATE(IF('Cap Quote Request '!L6=0,"",'Cap Quote Request '!L6),IF('Cap Quote Request '!L7=0,"",'Cap Quote Request '!L7))

I am pulling together two words from another sheet. It works except instead of the words showing up as

Dog Cat

Its showing up as

DogCat

with no space. Could anyone please help me with this minor snaffu. Thanks in advance.

I changed it to

=CONCATENATE(IF('Cap Quote Request '!L6=0,"",'Cap Quote Request '!L6),TEXT(" ", ),IF('Cap Quote Request '!L7=0,"",'Cap Quote Request '!L7))

That got it.
