Template question: is it possible to ignore an empty variable?

I have this template to populate #percentread from the runtime chain variable "Current_Page":

Code:

program:
	totalpage = $#pagecount;
	currentpage = globals(Current_Page=1);
	newpercent = round(multiply ((currentpage / totalpage), 100));

Currently, if I leave Current_Page empty, it defaults to 1 and newpercent does math based on that.

Is there a way to instead ignore an empty variable and leave #percentread unmodified?
