On Error GoTo line... doesn't work. Why?

[Dzony]

Hi, I have problem with On Error statement

When I use my code sometimest there is no file that I need (StrFilename2, and StrFilename3) and I need an error statement. First statement works ok (On Error GoTo line1), but second not (On Error GoTo Line2), could you tell me where is problem from this part of my code?
I will be grateful for your response
