I have three fields: BusUnit, SLType and SLNo
I need to write code or rule that will check the first character of "BusUnit" and if it is a Letter then it makes the "SLType" and "SLNo" fields mandatory.
Is this possible?

Thank you Simon Muntz!
What if the first character is not a number or a letter (shouldn't be) ? I am thinking it was then make the 2 field mandatory even though it is not a letter. I don't want them to be able to type any special characters either. Just A-Z or a-z or 0-9, That should be a RegEx expression validation for field as well, correct?
