Hi Jake,

Again, thank you so much for your help - As I said at the start I'm a complete novice so thank you for bearing with me

I followed your advice about the indentation and have found the issues with my 'End If' statements I didn't realise something so simple would help so much!
Thank you also for the help in defining strings for the username & password aspects! I've now got the script to a place I'd like it to be So thank you so much for that!

I do have one last question - With the IP address validation that's now in place I'm encountering an issue where if I copy a cell from Excel with an IP address inside and then run this script in SecureCRT it doesn't recognise it as an IP address whereas if I copy the IP address from within the cell the validation is happy with this - Do you have any ideas as to why this is? It's not a huge issue, just a bugbear This used to work fine before the validation was in place so it seems that when the Excel cell itself is copied something else is in the clipboard along with the IP address to cause the validation to believe it's not following the IP address conventions

Cheers,

Zander
