URL for repeating template page going to wrong page

Bit of a strange one - I have a template page set up in PowerCMS which displays different surveys. It's been up and running for ages with no issues, however the latest two surveys which I've added aren't behaving as they should. The URL for survey 1 is taking me to survey 2, but the URL for survey 2 works fine. It seems to be an issue with a hyphen in the URL as it works when I replace the hyphen with a space, i.e.:

https://www.mysite.com/survey-detail?ID=Survey-One - goes to https://www.mysite.com/site/survey-detail?ID=Survey-Two
https://www.mysite.com/survey-detail?ID=Survey%20One - goes to the correct place

I've checked the database and all seems to be fine. Any idea what might cause this?

I'd need FTP access to debug this. I'm not sure exactly what is going wrong, but I'm sure I could figure it out if I could access the files.

That would be great, details in PM.

You named the survey: "Cisapride Survey" not "Cisapride-Survey"

The link has to match the survey name... so that is why it isn't working.

I updated the page so that you can use dashes and spaces interchangeably so that both links work.

Ah, I thought I'd already done that but now that I look at the previous ones I had included a hyphen in the ContentGroup field which explains why they were all working. Thanks for sorting!
