LogicGate uses the standard JavaScript RegExp constructor for validating Field input values entered by end-users. Certain Field types allow the entry for a RegExp validation string which will check against the input value. 

For example, to create a validation that would require the user to enter the letter A, B, or C followed by 4 numbers you would enter the validation string of 

^[A-C][0-9]{4}$
