So maybe explode by commas, then explode by "\D" to get ranges?

John,
I think you've missed my point. I'm currently 'exploding' by ',' to give me sub ranges and then 'exploding' the subtranges by '-' to get the actual start and end, adding the subtotals up for the page count. The problem is that I want to be able to replace the different types of '-' that can come through, without knowing what they might be using.
In short I'm looking to search for any character that is NOT one of the following:
"0-9 cdilmvx ," and replace it with '-' [chr(45)] (I do an initial strip of spaces at the beginning of the process).
Cheers
George

Actually, what you need is split() by the sounds of it. Spliting the groups of pages by ',' would give you an array of either single pages or ranges of pages. From there, it is just a matter of mathematics to take the pieces of the new array and adding them together.

Hi,
I don't want to spend a lot of time leaning how to use this function but I have a problem that I think it can solve.
I have a web form that allows the user to (amongst other things) submit a pagerange to my database. Using '-' and ',' as separators, I am able to calculate the number of pages being submitted.
I can handle roman or arabic numerals and a typical range might look like: 'ix-xxvii,21-30,64' and that would usually give me a page count of 30.
The problem is that I think that some of my users are pasting the range in, rather than re-typing (I don't really want to stop them from pasting) and I am sure that sometimes the '-' is coming over as something other than a conventional hyphen.
Can anyone suggest a filter that will handle my hyphens correctly, regardless of what type of hyphen the user is entering?
