[amibroker] Any Help Please error in code

["Hetal" <hetal_mba@xxxxxxxxx>]

Hello Friends,

I get an error5 Argument #1 has incorrect type (The function expects 
diferent argument here)
Dono whether i am doing this is right or dono where i am going wrong.
What i want is in intraday mode i am tryinmg to pull full days todays 
volume and comparing it with prv days volume
To get prv days is far i cant get to the 1st step any help would be 
appreciated.
The code giving the above error is as below:

a6=TimeFrameGetPrice(Foreign("NFCE1_3100","VOLUME"), inDaily ,0); // to 
get today's total volume till now in intraday mode

If this is solved i would also like to compre it with prv days's vol 
also.
Thanks in advance

Regards
