I can't figure out why this script does not work

I am trying to run a script that is from Backblaze to install their desktop client. I think I have everything working right but I keep getting this error. Any help is greatly appreciated:

Is param the very first non-commented line in your entire script? If anything is put before that, you will get that message.

yes, it is. Thank you for your response.

Gotcha. Looking at it a bit more not on my phone now I see it says Line 4 char 1… Is your BBEmail variable correct in Syncro as well? It almost looks like the character is messed up unless that happened when you were pasting it.

I ran it through my instance and it runs fine.

Yeah, that was the problem. I figured it out just as you sent this. Thank you!

Hey there I’m using the same PS script from Backblaze and trying to run platform variables from syncro in it. The same error is coming up and the install keeps failing. Either Param is not recognized - Was this a formatting issue from the script that was copied?

Hi there,

This happens because when you use a script variable in a Syncro script, the variables will automatically be injected into the top of the script when Syncro runs it. This makes the “param” keyword not the first line in the script, leading to an error.

I am not aware of any workaround to this.
