TOPIC:

Hi,
When i use the plugin and i put, for example, this condition:
Weight<10; Shipping=10, i receive back this:

Evaluation yields unknown value while evaluating rule part '<'.

What can i do ?

Hmm, that's strange. If I use this rule, everything works just fine without any warnings or errors:
Is this really the whole rule you are using?
Can you reproduce the problem on demo.kainhofer.com/ ?

Best regards,

Hello there, I am having this exact same problem so I thought I should post it in the same topic? I was previously using the standard shipping plugin and the code I used worked. When I enabled the advanced shipping plugin and copied the same code over, I get the error:

Evaluation yields unknown value while evaluating rule part '<'.

The code I'm using is:

Name=Carriage Charge; 0<=Amount<79.99; Shipping=7.90
Name=Free Shipping; 80<= Amount; 0

Many thanks.

Can you update your plugin to the latest version 4.1? I have no idea what causes the problem, but it appears that it no longer happens in Version 4.1.

Best regards,
Reinhold

That worked! Thank you very much!

Problem solved.
