should I be using REFindNocase in this case?

Hi,

I need help on the function REFindNocase. The project is old and still using CF9 so there is a limitation on what can be use.

Each student has a different BookSelectList. Example: it can be NULL (which allows them to see all books), or 1 (which allows them to see only Book A) or 1,2,3 (which allows them to see only Book A, B, C)

We have the below:

<cfif REFindNocase("(1|2|3|4|5|6)",#Selection.BookSelectList#)>

    <cfinclude template="showbooks.cfm">

</cfif>

Which works fine until we hit book 10, since 10 consist of "1". REFindNocase will return 1 and display something they are not meant to see.

What can I do to avoid that? Can REFindNOcase compare Numbers instead of String? If so, how it can be done?

Thanks in advance!
