Hi,

 

I would like to find the index number for a given record ID. Here is example,

 

markRec = market [ID=123456];

 

and then find the index number

 

indexRec = market[ID!=0] range from markRec.index to markRec.index;

 

Reason for doing this:

I can build a next or previos button to fetch the previous or next record.

 

Any suggestion?

Many thannks.
