Value is invalid. | Incorrect tag type. | Check if the tag type corresponds to |
|
| the data type. Is the data a floating |

| Incorrect data mapping. | Check if the tag is accessing the cor- |

|
|
|
| Incorrect primitive on the display. | Check if the primitive corresponds to |
|
| the tag type. For example, primitive is |
|
| a Text Integer so the tag has to be an |
