i think that's right too.....we use than in comparative and then we use as a link word. we don't use then as a comparativeI did it right.

"Than" is a conjunction used after comparative adjectives and adverbs, after expressions of preference, etc.
"Then" is an adverb of time, which means "at that time", "in that case", "as a consequence", "immediately or soon afterward"
