Cause

You have a syntax error in the declaration of a local variable. When you declare a local variable, you must assign it an initial value.

If the snippet of expression shown in the dialog doesn't seem to have anything to do with a local variable declaration (or is blank), and the position of the error shown in the dialog is at the beginning of the line, it means you have a new-line following the name of your variable, e.g.:

 Var x
  

Or in this this case:

 Var x
 Sum(x+y,I)

you'd see:

 Sum(x+y,I)
 ^
 expected :=

That's because Analytica allows you to place whitespace anywhere in an expression, and the fact that the := is missing doesn't become evident until the line following the Var x declaration. Hence, the dialog displays the line following. In these cases, be sure to look at the line preceding, which will be a local variable declaration (Var..Do, For..Do, MetaVar..Do, LocalAlias..Do, etc.)

Remedy

In the For loop case, provide the set of values to iterate over, e.g.:

For x:=I do u

In the declaration case, provide some initial value, even if it is just Null or 0, e.g.:

Var x:=Null;
...
