One problem with the code above: there is no setprop for dgIndexes in  
the version of the data grid you have. You can add the setprop to btn  
"data gird" of stack "revdatagridlibrary" though. Just find getprop  
dgIndexes in the script and add the ollowing after (just make sure you  
set the preservevariables to true beforehand so the script locals  
aren't wiped out).

setprop dgIndexes pIndexes
     put pIndexes into sIndexSequencing

     lock screen
     _ResetIndexesOnControls
     _RedrawList
     unlock screen
end dgIndexes
