write name checking function where case sensitivity does not matter

I'm having trouble writing a name checking VBA code where case sensitivity is removed.

Given:
uName is a string
Worksheet 1, A1 = Cow

uName = cow

if uName <> Sheet1.A1.Value
do something

For some reason, case sensitivity matters. If i changed it to lower case C, it would work. I'm assuming excel changes the letters into values. Maybe I should set uName as an integer? I have no idea. Can someone help?

Thanks

... at the top of the module.

I recommend Martin's approach, though.

I'll give it a shot. Yeah, i was just writing in pseudo code. It's easier to read... and write.

thanks, worked. i just ucased everything.
