The value entered does not match the format of the field
I have created a very simple fillable pdf document for merit increases. I have two fields that are used to calculate a percentage increase of salary. Set up as follows:

The issue is that when there not a number in the recommended salary field, I receive the error message that "the value entered does not match the format of the field (percentage increase)". I set up the following calculation within the properties:

I cannot distribute the form if I am receiving any type of error (even though the work-around is to leave a number in that field at all times). Any suggestions as to how to fix this?
Thank you!
