dollar condition problem
Posted: Mon Apr 29, 2019 9:09 pm
Hi,
I have to use the if statement for my model. But I get an error for this equation. Why didn't I get the error? I'd appreciate it if you could help.
Eq.. const26(m,t).. sum((i,k),A(i,m,k,t))($sum(i,d(m,t,i)) gt r(m,t)) =e= sum(i,db(m,t,i)) ;
Error:
**** const26(m,t).. sum((i,k),A(i,m,k,t))($sum(i,d(m,t,i)) gt r(m,t)) =e= sum(i,db(m,t,i)) ;
$37,409
37 '=l=' or '=e=' or '=g=' operator expected
409 Unrecognizable item - skip to find a new statement
looking for a ';' or a key word to get started again
