I have to strings, each variables ($correctAnswer & $userAnswersAll).

They are both of 225 character length. I can output their string values and string-length. But when I try to compare them together all hell breaks loose.

If even tried comapring the string lengths against each other, still no luck:
<xsl:if test="string-length($correctAnswer) = string-length($userAnswersAll)">
    <b>Well done. All correct!!!</b>
</xsl:if>

Any help in this area would be greatly appreciated. Thanks.

(Debug off, press check under puzzle. Puzzle contains correct values for testing purposes).

Sorry, but I doubt that "all hell breaks loose" is a particularly precise description of the symptoms you are seeing. It's certainly not good enough to diagnose the problem.

Usually when someone submits three lines of code and says they don't work, it's because the problem is somewhere else. (As my grandmother used to say, if you can't find something it's usually because you're looking in the wrong place).

I apologise. 'All hell breaks loose' was a bit over the top! :)
