Thanks.

Sounds like you're using a continuous (or datasheet) subform. If so you're only option will be Conditional Formatting. Something like

Code:

Field Value Is    Equal To    "Some Value"

then set the Enabled property of the control.

Thanks for your response.Actually i have two field one it type and second is price.I just want that if type='y' then disable price and if price='z' then enable price.

You'll still need to use Conditional Formatting. I am not in front of a pc right now so can't test it, but it would be something like;

Expression Is FieldY = X

Then set the enabled property.
