I have a user code which always starts with "T21"...it can be T2112JSA2 (or any # of digits/letters after the initial "T21"
How do I set this as the input mask for a field?
I want it such that, when user double clicks on cell A2 (or clicks on A2 and then formula bar), the "T21" should be already there
Is this possible? If then how?
