warning Advanced Shipping by Rules for VirtueMart

[2cool]

Hi after update I see this warning:

Unknown variable 'Amount' in rule 'Amount=100'
Syntax error during evaluation, RPN is not well formed! (Full rule: '=Amount')
Unknown error occurred during evaluation of rule '=Amount'.
Outstack:

Array
(
   

• => Amount
      [1] => =
  )
  
  Assignments are not allowed inside expressions (rule given was '=Amount')
  Unknown variable 'Amount' in rule 'Amount=200'
  
  I noticed some customers don't see right options in cart.
  How can this be fixed?

I assume its your php 7.3 .. try 7.2

as u know the developer doesn't support his plugin anymore but I am using it successfully on various sites vm3.6.8 with php7.2
haven't seen this error so far but don't use any Amount rules

Thank you,
I know support ended. Guess php is causing this.
Hopefully someone here knows how to fix this.

Was a post already but not sure if this should fix.

This fix didn't work for me. I basically gave up on it a month ago. If you manage to figure something out please let us know here, 2cool.

I could update it. Write a ticket at extensions.virtuemart.net/ticket

Milbo do you mean Advanced Shipping by Rules for VirtueMart? please do it's very nice.
But could this issue also be related to php 7.3.1? are there isues with this version with virtuemart?

Thanks,
