Family table in MS Excel: double value required

When entering a dimension value in a family table, Excel warning window (Validation failed) pops up and says "double value required". What is a double value? Why does a dimension need a double value? Why is it required by excel? How to bypass this warning message?

ACCEPTED SOLUTION

Found the culprit: conflicting family tables with the same name/reference. Deleted the idx-file and the warnings stopped appearing.
Still no idea what the double value means

Don't forget to mark your answer as the correct one for those who will see this post later on.

Just a guess, but generally speaking there are "float" variable types that represent real numbers with 32 bits. A "double" real number representation has twice the number of bits (64), higher precision, and can cover a larger range of values. Something in the data you were originally dealing with must have been considered "illegal" by Excel for it to convert to/from a double value.
