Conditional check in VbScript

Hi,

In this script the input filename is passed as a parameter at runtime  (Thanks to Idle_Mind ;)

Like so...
strOrigFile = WScript.Arguments(0)

And at runtime...
wscript C:\testing\csv_to_xls.vbs C:\testing\in.csv

Now I want do do a conditional statement after this, basically saving if you cannot open the input file then just give up and die gracefully, currently if the file does not exist the script exits with error on line 23
objExcel.Workbooks.Open strOrigFile

Can somebody please help?

Thanks

Rob
