Hello,
I seem to have a problem in my code written in the When_radio_changed
trigger of a radio group called "TYPE" and the reutn values are set as "w" in one and "r" in the other radio button... and here is the code :
if :TYPE='r'
then set_item_property('TEX_P_ID',Visible,'Yes');
else if :TYPE='w'
then set_item_property('TEX_P_ID',Visible,'NO');
end if;
end if;

the error i : FRM-41046: invalid parameter used for set_item_propery.
Can Anyone Help PLease?

1) Is VISIBLE a valid property for SET_ITEM_PROPERTY? It may be, but I can't remember for sure. Check the Forms online help.

2) I do know that 'Yes' and 'NO' are not valid values for the 3rd parameter. You should use PROPERTY_TRUE and PROPERTY_FALSE (note: without quotes).
