[amibroker] Time Function or Foreign error - Need Help

["wooziwog" <xcitemint@xxxxxxx>]

I have tried to get the following formula to work and am definitely 
in over my head on this one.  I am trying to accomplish the following:
1.  Set the Time frame to daily and get yesterday's close(vxdc)
2.  Set the Time Frame to one minute and get the most recent close 
(vxmc)
3.  Subtract vxmc from vxdc for vxdif
4.  Use vxdif for plot and color
I appreciate any help that can be provided on this one.

//Vix Barometer//

TimeFrameSet( inDaily );
vxdc = Foreign ("$Vix","C");
TimeFrameSet( in1Minute );
vxmc = Foreign ("$Vix","C");
TimeFrameRestore();
vxdif=(vxdc-vxmc);
Plot(vxdif,"vxdif",C);
COLOR=
//Ultra Bullish Reading//
(vxdif>=-1.20)*colorGreen+
//Bullish Reading//
(vxdif>=-0.80)*(vxdif<-1.20)*colorBrightGreen+
//Neutral Bullish Reading//
(vxdif>=-0.30)*(vxdif<-0.80)*colorSeaGreen+
//Neutral Reading//
(vxdif>=-0.30)*(vxdif<0.60)*colorBlue+
//Neutral Bearish//
(vxdif>=0.60)*(vxdif<0.80)*colorYellow+
//Bearish//
(vxdif>=0.80)*(vxdif<1.05)*colorLightOrange+
//Bear Ugly//
(vxdif>=1.2)*(vxdif<1.50)*colorRed+
//Extreme reading, look for Market Turn//
(vxdif>=1.5)*colorRose;

Plot( 10, "Ribbon", COLOR,styleOwnScale|styleArea|styleNoLabel,2,5 );
