OPEN external File on visu


By the codesys visu, on runtime mode, (inside Automation Build 1.2), i should be able to open an external file (probably .pdf), by a button. The file and his name are not 'constant', but will change under some conditions.

I configured a button that open a file .pdf that have a name prefixed and it works correctly.

I configured a variable 'string' for the name of document, linked to the file's name (which that changes daily...); i created a new button that should open a file 'variable.pdf'.

But does not work.

I checked path and more, but does not work.

How could i fix it ?

Thanks for the tips
