Field Calculation problem~
I have build up two field, one is for imperial and the other one is metric, how can I set up the calculation function to build its relation?
For example, if I type 1 inch in imperial field, the metric field will automatic show up 2.54 cm. In opposite, if I type 2.54 cm in the metric field, the imperial field will show up 1 inch.
I have try to use the calculation function in metric field "imperial field= metric field / 2.54". but the problem is I can not type the number in the imperial field and then calculate back.
How can I solve this problem?
Thanks for your help
