Open Next Bar

[TradeWynne@xxxxxxx]

Does anyone know a work around for using "open next bar" with a second data 
stream? 

For example: If C of data2 {daily data} > xaverage(C of data2,5) then buy at 
open next bar  {intraday data} + 10 point stop;

Produces message : "Cannot mix next bar prices with data streams other than 
data1."

Thanks,
