Match a variable to another variable

In the tool I use an IF condition where I want to match a variable a with a variable b plus an expression, the name of the variable a is the same as the variable b, but the variable b contains a number forward that makes the names different, as I can make them match in an if condition

How to concatenate two variables within an IF condition in Workfusion?

@Gamaliel use the Constant Value action to form the final expression that you need to match the variable against and then use the resulting variable in the IF condition.
