There seems to be issue with the parsing of complex expressions with multiple items in the equal, the following code works  
for K=2:NZ1  
for J=2:NY1  
for I=2:NX1  
HXS[I,J,K],HYS[I,J,K],HZS[I,J,K]=  
HXS[I,J,K]-sum(ygradkernel[0,-1:1,0].\*EZS[I,J-1:J+1,K])\*HCRLY2[IDONE[I,J,K]]+  
sum(zgradkernel[0,0,-1:1].\*EYS[I,J,K-1:K+1])\*HCRLZ2[IDONE[I,J,K]],  
HYS[I,J,K]-sum(zgradkernel[0,0,-1:1].\*EXS[I,J,K-1:K+1])\*HCRLZ2[IDTWO[I,J,K]]+  
sum(xgradkernel[-1:1,0,0].\*EZS[I-1:I+1,J,K])\*HCRLX2[IDTWO[I,J,K]],  
HZS[I,J,K]-sum(xgradkernel[-1:1,0,0].\*EYS[I-1:I+1,J,K])\*HCRLX2[IDTHRE[I,J,K]]+  
sum(ygradkernel[0,-1:1,0].\*EXS[I,J-1:J+1,K])\*HCRLY2[IDTHRE[I,J,K]]  
end  
end  
end

The following code does not work (only change in position of +)  
for K=2:NZ1  
for J=2:NY1  
for I=2:NX1  
HXS[I,J,K],HYS[I,J,K],HZS[I,J,K]=  
HXS[I,J,K]-sum(ygradkernel[0,-1:1,0].\*EZS[I,J-1:J+1,K])\*HCRLY2[IDONE[I,J,K]]+  
sum(zgradkernel[0,0,-1:1].\*EYS[I,J,K-1:K+1])\*HCRLZ2[IDONE[I,J,K]],  
HYS[I,J,K]-sum(zgradkernel[0,0,-1:1].\*EXS[I,J,K-1:K+1])\*HCRLZ2[IDTWO[I,J,K]]  
+sum(xgradkernel[-1:1,0,0].\*EZS[I-1:I+1,J,K])\*HCRLX2[IDTWO[I,J,K]],  
HZS[I,J,K]-sum(xgradkernel[-1:1,0,0].\*EYS[I-1:I+1,J,K])\*HCRLX2[IDTHRE[I,J,K]]  
sum(ygradkernel[0,-1:1,0].\*EXS[I,J-1:J+1,K])\*HCRLY2[IDTHRE[I,J,K]]  
end  
end  
end

Please put you code in code blocks using ``` above and below the code, then we can read it 🙂

It also helps if it’s indented - 4 spaces is the standard.

But it looks like you have moved the `+` to the start of a new line - and that just doesn’t work in Julia syntax. You need to leave it at the end of the previous line to indicate that the line continues.

Thank you good to know.
