Hello folks,

So within the function I am using in nlinlsq, I have a common block that contains some global variables that are found within my main routine and used in my function (for simplicities sake it's called ddr). Since nlinlsq works on a "number of functions" basis you pretty much have to recast everything as 1D. I would like to check within my function if a value of one of my arrays is 0, yet the if statement keeps giving me an error of " Expression must be a scalar in this context: <BYTE Array(5)>." Below is a sketch of the code. Thanks in advance!

pro auto_target_offset

common offset_vals3,blah1,blah2,blah3,...,blah13,aoffxc,aoffyc
...
solution=nlinlsq("ddr",5,3)
...
end

function ddr,m,r

common offset_vals3 (same as above)
...
if aoffxc eq 0 then w=0
...
end

Thanks again!
