string not recognized in command line

[TNH]

Hi
I am trying to use 7zip with QM.I would like to zip selected files from file explorer. I created a string with the paths.

str ft

I checked the string during the process  , it looks good.
When i put the whole path in the command line the zip file is correct.

RunConsole2 "C:\7-Zip\7zg.exe a C:\Users\123\Downloads\test.7z C:\Users\123\Downloads\wn.txt"

When I  substitute the whole path with the string in the command line it is creating an empty zip file.

RunConsole2 "C:\7-Zip\7zg.exe a C:\Users\123\Downloads\test.7z ft"

I am attaching the macro.
Can somebody help me please?
Thanks
TNH
