Don't enter them as a number (because they aren't; they are text
references), enter them as text.
Either format the cells as text before entering the references, or precede
them with an apostrophe (which will not show)

Hello i am trying to figure out some basic sums but the forulas will not
differentiate between two numbers if one begins with a 0. in other words
if i
enter the number 3 in a cell it give me the same results as if i entered a
03. i need it to be able to diffentiate between the two as they are two
seperate references.
=SUMIF(B$3:B$16,"03",A$62:A$75)
