From Active Worksheet Trying to Open another file, cut, paste to original file; works in debug but shortcut fails

[kmblush]

Hi - I'm old to programming but very new to VBA. I'm using Excel 2010 and have a pretty functional routine. Where I'm running into trouble with opening a 2nd file, copying a column, pasting the column to the original file (from which the code is being executed) and then closing the 2nd file. Everything works just fine in Debug or if I access Macros from the Developer toolbar/ribbon and then select run. The process hangs if I use the defined shortcut. And, by hanging, I mean the 2nd file opens and then all processing stops.

The code snippet where the "stoppage" occurs is:

BlanksName = "c:\users\kathy\documents\Shipping Manifests\AllBlanks-" & MarketName & ".xls"
Set BlanksFile = Workbooks.Open(BlanksName)
BlanksFile.Sheets("Worksheet").Columns("A:A").Copy
BlanksFile.Close
WsSrc.Columns("J:J").Insert shift:=xlToRight

All variables have been previously defined. Any suggestions?

Thanks very much.
