[amibroker] Date of a previous Buy() signal

["dralexchambers" <dralexchambers@xxxxxxxxx>]

Hi,

I am trying to format the date of a previous Buy signal to a string:

a = "";

for (i=1; i<BarCount; i++)
{

if (Sell[i]==1)
{	
a = a + DateTimeToStr(ValueWhen(Buy,DateTime()));
}

}

However, the "a = a+..." line does not work. I get "Error 
5....Incorrect type".

Can anyone advise?

Oh - I need the loop to stay intact (ie. the "if (Sell[i]==1)..." 
code), as I have other processing code in this loop.

Thanks.
