Bring Data in RtReports from an OPC Tag depending on the state of another OPC Tag

Hi:

 

I have two OPC tags, one giving me the steps on a process and another giving me the pH values.  The thing is that I need to bring the maximum value of the pH only when the step tag reads 14 (step 14). I don't need all the other registered pH values.

 

I there any way to do this? How can I tell the system in RtReports that I only need that specific period of data? Is there a way to use something similar to the "while" instruction in other languages or tell the system I need the max pH "during" a certain stage in that other tag?

 

I know both tags will have different time stamps, but is there any way to relate them?

 

I'll appreciate any help with this.
