How much effort are you willing to put into finding a solution? If you put
no more effort into it than asking someone else to do it for you, you are not
going to see many responses. There are several search engines on the net that
will help you find working code examples, and help you learn what a Dictionary
object is. If you want code handed to you, go find it on the net. A Dictionary
is similar to a Collection but with a few major differences.

I gave you an indication of how it could be done:

"I'll be interested in seeing who will decide to help out beyond simply stating you
have to split them up into words and use a dictionary to subsitute in the needed
parts.... "

Look up Split in VB help. It returns an array. So you split up the two input
strings which turns them into array of words. Loop through the arrays looking
for your %x tokens and associate the token of one array with the word from the
other array. How you associate them is up to you, you could use a dictionary or
a collection.

When you split the output string into an array, all you need do is loop through
that array looking for those %x tokens and substitute the associated word for
that token. When the loop is finished, you can use Join to put it all back into
a string for output. See Join in VB Help for examples of its use.

The newsgroups are not your personal developer resource, no one is paid anything
to participate. Most are here to share knowlege not give away code although,
code examples are a concise method often used to convey certain knowlege.
You are expected to research the problems and try to solve them yourself. You'll
find you will get many more responses if you post the code you've tried that
doesn't quite get the job done, instead of demanding that you want the entire task
completed, and only certain responses be allowed. As you've found out, no one
is obligated to post any code whatsoever, and if it appears you are not putting
much effort into solving the problem yourself, why should anyone else bother
putting more effort into it than you? Try the solution suggested, see how far you
get, and if you have problems, create a _small_ demo to show the problem so that
others can copy and paste your code and try it out to see it on their system. They
are much more likely to fix your code, rather than create a complete solution from
scratch.
