Validate to Look for specific text in a text box.
I want a text box that has a default of "Body System" so under Options I placed "Body System" and under Actions, I placed a code to erase the Default Value.

Under Actions:
Select Trigger: On Focus
I ran this code

Then in this same text box I want to check if the word Skeletal is included with the following under Validation:

So it works fine but if someone goes into the Text box leaves it blank and clicks out of the text box it gives the error message because they left it blank. I would like to run the validation only if they typed in the box, and if they type and delete to move to another text box I would like for the Default Value to come back into view.
