Hi Everyone,

 

I'm using the expression below to try convert all the values that are negative or equal to zero to NoData

 

SetNull("cov_fdg_ct" <= 0,"cov_fdg_ct")

 

But it failed to execute with the error message below:

I've been reading many posts from those who also got the ERROR 000539 and most of them seem to be due to a syntax error. However, I can't seem to figure out what syntax error is in my simple expression. It would be much appreciated if you can provide some advice!

 

Thank you!
