mandatory field to be filled

[johnlyons]

In a layout I have a portal with a field model and then dimesion fields A,B,C,D. pending on the model entered then various fields must be filled in as mandatory. Example: if Model 'E90' then only field A must be filled. If model 'TR' then fields A,B,C must be filled. If Model 'TC' Then fields A & C must be filled. Can the this be done so if these fields are not filled then a message appears?

yeah sure... goto the particular field you want in define database... then select it and click options, goto validation tab, do validation by calculation... specify your validation calc.. then down the bottom, still in the validation tab... select the show custom message or something check box... and specify a custom message... any more questions, dont hesitate to ask
