In the metedata editor for a table I have two fields

cMicrochip
cfk_dmicrochipreader

I only want cfk_dmicrochipreader to be enabled if cmicrochip is not empty

I have entered in the metadate entry

formitem.enabled
empty(cmicrochip)
F

and another entry
formitem.enabled
!empty(cmicrochip)
T

This does not however seem to work in the section where the field is. I can only assume I have the syntax wrong.

Please can someone tell me how this should look.
