I can't see your program however what I have found with Fanuc .LS files is if you have labels in your I/0 or registers you need to remove them.
Example: IF R[1:GI[3]=Part_Lengt]>=88 AND R[1:GI[3]=Part_Lengt]<93 AND R[2:GI[5]=Part_Width]>=10 AND R[2:GI[5]=Part_Width]<=20,JMP LBL[78]
To:
IF R[1]>=88 AND R[1<93 AND R[2>=10 AND R[2:GI[5]<=20,JMP LBL[78]
I copied the .LS file into excel and used the replace function as i had 400 lines of the same label use the paste back into the .LS file. When you load in into the robot the labels should come back in to the instructions. hope this helps.
