Shot in the dark here since you didn't provide the problem code, but this is how 
you *should* use the if/else:

if CONDITION: # CONDITION is an expression evaluating to True or False
     DO_SOMETHING # some statements executed if CONDITION evaluates to True
else:
     DO_SOMETHING_ELSE

Pay attention to the indentation and the colons. A less abstract example:

username = raw_input("Your name: ")
if username == "Valeri":
     print username, "has a question about if/else"
     # do more stuff
else:
     print username, "is an unknown user"

Yours,

Andrei
