Solver

Hello everyone,

I have a problem with adding a function as a solver to my panel. It shows an error such as : the file name or path doesnt exist,

the file is used by another program,

the workbook you are trying to save has the same name as a currently open workbook.

However, none of the above is open or used.

I am looking for help asap. I have exam soon.

Kind regards,

Suzanna
