Index & Match with IF statement

Good Afternoon,

I have an Index against 2 matches, but i need to add an IF statement to it if a cell contains a number, here's the formula

=IF(T12="1",(INDEX(Extras!$A$1:$G$6,MATCH($AK$10,Extras!$A$1:$A$7,0),MATCH('Traffic Sheet'!$H12,Extras!$A$1:$H$1,0))))

i think that i have been trying to work it out for too long and can't see the obvious solution.

help me please,

thanks reg
