searching for a test set using FindTestSets

Hello,

I have the below code to search for a test set. It works fine if the test set exists. If it does not exist, I get an error saying object required: tsList...... at the last line.

Set testSetFolderF = tdc.TestSetTreeManager
Set tstSetFolder = testSetFolderF.NodeByPath("Root\Test")
Set tsList = tstSetFolder.FindTestSets("V13")
total = tsList.Count
