Lookup Decimal Field - On edit Form data does not appears

Hi,

1- Maybe I'm doing something wrong, but i have created a Lookup field to import data from a Decimal field.
In the form it works fine, but in the edit form (at the report Views) this field does not recover the data that i have put in the submitted form. It means that when i update from edit form, the data in this field change to null.

2 - My intension in my form is to give the change to users submit several hours (several beginnings and ends). Please consider make a Creator field only with hours/minutes (more intuitive, like a analogical watch with pointers to drag and select).

3 - Is it possible in a loockup field connected to a number/decimal fields to display any text? (example "09h30")

Thanks for all of your great support!
