Fix for "leave weak side of splits" option?

[Daeymien]

Forgive me if this has been covered elsewhere, I couldn't find anything on it.

Reference: line 105 of ialias4.mrc

$calc(%lastct. [ $+ [ %chk.chtouse [ $+ [ $iNetwork ] ] ] ] * .45)

will consistently return a value of 0 as the variable it performs the calculation on doesn't exist.

so far as I've tested it, changing to the following accomplishes the job as intended.

$calc( %lastct. [ $+ [ $iNetwork ] [ $+ [ %chk.chtouse [ $+ [ $iNetwork ] ] ] ] ] * .45 )
