I am using Regular expression validator during the create transition.
I am using [a-zA-Z0-9_=+-] because I need to allow special charterers (_,+,-,=, ).
Am I doing something wrong because this is not working and throwing error whenever i place '_' symbol.
Sometimes you need to escape certain characters in order to have regex search for them. Since the syntax can be a little different depending on the interpreter. Instead of using your string of
try this one
The character of '\' can be used to tell a regex to search specifically for the next character and not use that character's special regex function. I don't know of any special function for the _ character in regex, but I think you can still try to escape it incase it is causing this to fail to match a character set you are looking for.
