Ignore statement

I am using the following piece of code which works fine when there is data to collect

strRange = Left(strRange, Len(strRange) - 1)
.Range(strRange).Copy

But it falls over with the statement 'Invalid procedure call or argument' when there is no data.

Could an expert out there provide me with the code that will move the code past this so that it does not fall over when there is no data

Thanks
