That's what I did. Thanks for the answer 🙂

Can you tell me why it doesn't make sense? That was not my question and it is certainly not my call here... just started working with the team!

Yes. When the filename is hear coded... it works!

I will send you the value of "filename" monday morning from work. Thank you 🙂

Unfortunatly, I work for the federal government. We cannot use whatever software of version we want here 🙁

Any other idea what it can be?
