I keep an getting error or the wrong result when I run the following:

FOR i = 1 TO 8
req_date = ('THISFORM.t_req_date'+ALLT(STR(i))+'.Value')
? ' Requested Date/Time = ' + DTOC(&req_date)
ENDFOR

I grab 8 date/times off of my form (out of textboxes) and print them to a file for printing. The "?" line prints a line for each date/time, but the date either prints without a time next to it or I get a syntax/run-time error. I have tried many variations, but I had it working once and then it has not worked since. Please help. Thanks very much.
