[Closed] Excel Experts - Help please.

One of my team has not been paying attention when entering data in a data field on a Macro'd excel file.

Basically there are four data fields.
The user enters numbers in each field, then they hit a button on the page labelled "generate part number" and a few moments later, a result is displayed in another field towards the bottom of the page.

One of my team has done something while not paying attention and now two of the data entry fields has shrinking text/numbers.

Each time the user clicks in these two data entry fields, the numbers become so small as to be unreadeable.

How is this fixed ?, please.

Thanks in advance.
