Error in set modifier expression

[caolu1995]

Hello All,

I created an expression  but unfortunately it is not working:

if([stage]='初步接触', Count (total(projectNo)),
if([stage]='试点试用',Count (total(projectNo))-count({<stage<={'初步接触'}>} projectNo)))

Set modifier error could be removed by removing additional '<' in your expression:

count({<stage<={'初步接触'}>}
count({<stage={'初步接触'}>}
