Each company has its own set of rules for how the tracking number is structured, so its fairly straightforward to use a regular expression in order to pick apart the number.

The line is "[if tracking_number =~ /^[0-9]{12}$/]" and it should return true if the characters are between 0-9 and the number is 12 digits long. Is it possible to compare a variable to a regular expression in the "if" tag? If so, am I doing the regular expression comparison incorrectly?

Hi Mihai,

I suspect you’re just needing to specify *which* variable is getting compared against; try `[if scratch tracking_number =~ /…/]` to test the scratch variable in question.

HTH,
