Help with elsif statement - syntax error?

I'm trying to add a series of elsif statements to my formula, but it is coming back with a syntax error. Any ideas?

if field("short_description") == 'How do I cancel?' then '0270c251c3200200be647bfaa2d3aea6'
elsif field("short_description") == 'I'm having an issue' then 'c54de838d7b122004f1e82285e61036b' end
