Hi Michael,

I have tried all of your suggestions as well as some new ones but it still doesn't work. I am not trying to think in "and then add...".
But I thought you or other readers might not understand what I am trying to explain so I thought it might be easier to explain in "and then add...".

I tried your last suggestion and all I get back is 0 as my value.

Did you even look at my code that I sent previously?

Thanks,

Grace

Sure I looked at your code. It's calling sum(Time) when the context node is an IRD element, which is clearly wrong, as the IRD only has one child called Time, and summing over a single element will get you nowhere.

Hello Michael,

I understood what you are suggesting and I have tried taken out the IRD node and that it gives me the total of the whole <Time> for one Node which is not what I want. What I am looking for is a sub total from a particular time frame that's why I have to use the <xsl:when.. /> to determine if the <ST> and <ET> fall within the From and To node which is determined by $FromStart and $ToEnd.

Man, this is confusing. I was just wondering if you understand my question or am I misleading you into another question.

Whatever suggestion that you have given me, I have tried.

I apologize if I don't understand your suggestion. Can you be a little bit more specific to what I else I can do.

Did I mention to you that I am a novice at this.

Thanks and have a wonderful day!

Grace

Hello Michael,

I just want to thanks you for all of your help and pointers. I got it working now. I guess the problem that I was having with was missing the double slashes for the predicate!

Thanks and have a wonderful day!
