Webform Custom Validation, prevent cell from matching another

[David28196505l7e6]

I am trying to prevent a cell from being filled out with the same number from another cell. I was attempting to do this fieldValue != [Store Number] , but am gettting the error that the value of Store number can't be found, so it won't save the formula.  Any help would be appreciated, thanks!

Hi Meenakshi, 

Thanks for the reply. I am having trouble still getting it to do a field to field comparrison. I have a field named "Store Number" and a field named "Startdata" I don't want them to be able to enter the same number from the "store number" in the startdata field.  Most of the errors im getting are similar to this "The expression is not valid because it refers to the following fields which cannot be found: Startdata, Store Number" 

Any thoughts on how I can do a simple field != another field ?
