Setting range parameters from Delphi

[carynwn]

I am updating a generic report runner to use Crystals range parameters. Currently the code loops through the report parameters, setting the values.

So when it does this I ascertain whether the param is of value type vtRange, then attempt to set the RangeStart and RangeEnd values. When I do this I get an error at runtime about the value being set (parameters have to be strings).
