Could someone give some advice on how to solve the variable error? I know it is something simple, but I really have no idea how to return it, the operator put the amount and then put the letter "i" to multiply it and convert it to inches, but It no longer does it and the old files of woodwop 7 stopped showing correctly, so I think that after changing the configuration, do you know how to reset the configurations or take steps back?Here I leave the sample images, if you respond, in advance thank you,
