Non-queried default values not working

This is driving me crazy. I can't get non-queried default values to
work with non-queried string report parameters. I'm using Reporting
Services 2000. Here's a test case: I have a simple Report Parameter: a
string, called "Color". It has three non-queried label-value pairs:
Red-red, Green-green, Blue-blue. I then try to define a default
non-queried value of green. Run the report, it always says "Select a
value". If I change the label-values to single-digit values, like
this: Red-1, Green-2, Blue-3, and set the default value to 2, then
Green comes up as the selected value (which is what I want). But I
cannot use a string for the value - it never matches. I've also tried
two-digit numbers: Red-11, Green-22, Blue-33, and used 22 as the
default. Comes up with "Select a value".
Can you not use strings as default values?Found the answer myself. Yes, you can use strings as default values,
as you would expect. Everything worked great in the Preview pane of
Visual Studio (the defaults would show properly) but when I put the
report on the report server, the dropdowns would say "Select a value".
To fix it, I had to completely delete the report from the server, and
upload a brand new copy of the RDL file. It did not work to simply use
the "Update" option in the Report Properties web page on the server.
It would update the report (i.e., I could see other changes I made) but
for some reason, the parameters would not work properly until I
completed deleted the report and uploaded it again. Go figure.
