OK that's great...
Typebar = ParamList( "Typeofbars" , "UpBars,DownBars,AllBars");
Filter = Null;
if(Typebar == "UpBars")
{Filter = upBar;}
if(Typebar == "DownBars")
{Filter = downBar;}
if(Typebar == "AllBars")
{Filter = 1;}
...works a treat.
I think my main error was in not being particular about exact matches of
"Text" entries with respect to capitalizations and perhaps spacing.
I see the use of the *if* keyword does not have to have the *else* part
to work.
I also see that whether I use
Filter = Null;
or leave this out seems to make little difference.
I appreciate you time and input.
Regards.
