Hi!

I have same problem. Could you help me?
This is the source:

<dtml-in SelectState size=10 start=query_start>
<dtml-var expr="_['STATE']">
</dtml-in>

SelectState is a ZSQL method, gives the STATE,
STATE is an integer, and there are three DTML
DOCUMENT (named 0, 1, 2) in the folder,  and these
objects contains the "state string" (for example "OK",
"Connection error" etc.)

If I use the code above, I get only 0, 1 or 2, not the
state strings.

I tried <dtml-var expr="_[STATE]"> too, but it gives
these erorrs.
Error Type: SystemError
Error Value: bad argument to internal function

   Thank you:
