Need to insert an if statement

I have found that then running a procedure, that if a copy range is blank, it is failing.
How do I tell the following code to goto 201 'End of procedure if the .copy is empty?

Set UsdRng = Sheets("Sheet1").UsedRange
Set myRng = UsdRng.Offset(1).Resize(UsdRng.Rows.Count - 1, UsdRng.Columns.Count)

Fails on
myRng.Columns(1).SpecialCells(xlVisible).Copy

Only thing I can think of is that there is nothing visible to copy.  How do I do a if then on that line so that if there is nothing visible it will continue and if it is not it will do its stuff?
