I am trying to filter the results from a call to InterpolatedValues2 based on the value of a string tag.
With out the filter string the call works correctly
Set pvalues = ipdata2.InterpolatedValues2(StartDate, EndDate, Period)
I am trying to add a filter where the tag Grade.Current is equal to 'CPC1150000"
I have tried a few flavors trying to figure out the syntax but haven't found the magic.
