I'm attempting to use  to evaluate some numeric variables in a template, but apparently if the template boilerplate is copied to a page and some of the variables aren't filled out yet, then I get Expression error: Unexpected = operator.

Template: w:c:acecombat:Template:InfinityStatsAircraft

Example article: w:c:acecombat:F-4E -20th Anniversary-

Anyone have any ideas? The best way I've figured out how to solve it is by removing the = next to the boilerplate code used in the article next to each cost## variable, but that can get a little annoying and I'd like to learn why this is happening in the first place.
