Joshua is trying to establish a conditional format that will alert a user that text data has been entered into a cell intended for numerical data or when numerical data has been input into a cell intended for text data.
A conditional format can be used to draw attention to when an improper value (text or numeric) has been entered in a cell, but a more robust approach might be to prohibit the improper value from being entered in the first place. This can be done with the data validation capabilities of Excel. These capabilities have been discussed, in detail, in other ExcelTips; more information can be found here:
Using data validation, you can specify the type and range of data permitted in a cell, along with how stringently you want that specification followed. If you prefer to not use data validation for some reason, you can set up a conditional format that will verify if the information placed in a cell is of the data type you want. Follow these steps if you are using Excel 2007:

If you are using an older version of Excel, follow these steps instead:
