Soft limit setting trouble shooting

[chillybo]

Hi everyone, So I've built the 4 x 2 foot router and got it to home to proximity switches on the 3 axis. Im struggling to set the soft limits in particular Z soft limits in Mach 3 I've watched numerous you tube videos on the subject and followed accordingly but I must be doing something fundementally wrong. I got them to work and the machine stopped where I wanted but it wouldn't let me return to zero or home, saying soft limits out of range. Either that or the Z axis would not home. All the you tube videos showed Z soft minimum set to a minus number and soft max set to zero. I tried this but things got worse. Please could anyone look at my XML file attached and suggest what I am missing?
