PD: this issue only occurs when Q2 is on a separate group, please check the attached .lss file
I have recreated the situation, T01 T02 and T03 are questions for testing relevance, same questions have been copied on Group 02, and here you could get the error

Confirm the issu : javascript used after the second group show is broken

INput hidden value is 1.6 : the js wait a 1,6. Don't know if we need to

• fix EM PHP to return 1,6 in input
• fix EM js LEMval for hidden var (the no , to . test)
• fix EM js to update . to , before do other testing

Think better is ??? Maybe return always the real value : 1.2 , even if user write 1,2 (and allowed to write 1,2)

I think:
a) decimal values should have 2 values: internal value (1.6) and formatted value (1,6 or 1.6 depending decimal sep)
b) evaluations (ie relevance evaluations) should be done using internal value
c) input validations should be done using formatted value

So, I think the error is not the js in the second group, the error is that js should wait 1.6 in input for relevance evaluations in both groups, and js should wait 1,6 in input for input validations just in 1st group

Thanks a lot
