Witango-Talk: @REPLACE

[Roland Dumas]

I have a string that's in a variable. I want to do some string editing on it.

<@REPLACE request$mystring 'This string' 'That string'>

works just fine, but when I use a variable in the FINSTR argument, it does nothing

<@REPLACE request$mystring request$tidbit 'new string'> doesn't work

Yes, the string I'm looking for exists and is a part of the STR. Are variables disallowed?
