Converting symbol name

[sam123]

I downloaded with TS a data for S&P500 which named by TS : US500IDXUSA.
In my marketwatch the symbol for S&P is just S&P.
In that case, the tester does not recognize the data from TS for S&P.

How can I fix that?

I think I have managed to convert the name by using "Map to" in Metatrader info tab, in symbol properties
BUT
I still have a problem using this data since I get 2 errors in the log file when running a backtest:
1. "tester cannot calculate prices"
and
2. "Tester: exchange rate cannot be calculated".

Please help.
