Hi all,

Using the Umbraco interface, I'm having an issue passing a variable into the GetMedia function in the code below. If I hardcode the value 1065, the code works fine. If I pass in $mediaCollection, it fails to validate, but the value of the variable is 1065.

The interesting part is that if I select the checkbox to ignore errors, the XSLT file saves OK and it works. But with the box unchecked, it reports the error:

System.OverflowException: Value was either too large or too small for an 
Int32.

I've found other topics in the forums about similar issues, but haven't been able to resolve mine using their suggestions. This might be my understanding though.

It's not preventing me from progressing with my projcet, but obviously something is wrong, and it's best not to sweep these things under the carpet in my experience - they generally come back to bite.

Can anyone help?

Thanks
