When entering the MPS, i pressed on a hidden button with the shape of a "Bullseye" next to the Row "To Receive / To Supply / Produce " .
After clicking this button, it locked/greyed out the cells of this row. I clicked it several times to try and unlock the cells, however, now i have all 12 months locked and greyed out.
How can i unlock those cells to be able to set the min/max again.
P.S. i am working on a free trial online database.
