Error in trig question

[cat.b....@gmail.com]

Hi,

One of the questions that we have been using for years is giving an occasional error. I didn't write the question. The link to the question is below.

https://numbas.mathcentre.ac.uk/question/12818/trigonometry-right-angled-finding-reciprocal-trig-ratios/  

The error only occurs for a certain combination of variables and relates to the variable ans1recden

I can't see what the issue is as the 'if' command that is mentioned in the error does seem to deal with all combinations of the other variables listed.

I was wondering whether anyone else has noticed this issue and whether it can be fixed.

Many thanks,

Catherine

Thanks for posting this. I believe the issue was the innermost if (yes I should have used 'switch' instead) had a missing argument which meant any time that if-statement was accessed it had an error. Should be fixed now.

Would be nice if more people pointed out errors (I see a lot of people flag questions as 'has issues' but then they don't state what the behaviour is that caused them to flag it as such).
