txtValues() is a textbox control array of 3 elements....
i want to check through all three elements separately or together for ANYTHING other than a number...for now....checking for letters is fine..
If txtValues(i) contains only one character...how would teh check occur if the user typed "2b" in txtValues(0)

i hope this clears it up...not sure though

a, b, and c are single type since i need them in a calculation..
