For example:

<if condition=”$id eq  1”>

This is no problem

But if you want to compare two variables:

<if condition=”$a.id eq $b_id”>

This will cause problems

Solution:

Use the tag:

<eq name=”a.id” value=”$b.id”>

Note: There is no need to add the $ variable symbol to the name, but the $ variable symbol is required to the value.
