please tell me if you find any errors!!

 

@dec4234 Try without the dot in Snr.Mod the group and see if it works.

 

Try rather with the correct indentation on the snr.mod groupname first, but do expect the dot to still maybe not be acceptable

 

@dec4234 @bwfcwalshy @Boomer Found the problem
The Snr.Mod: is outlined from the others so just bring it back by one space and it should work
