getting a mismatch error after carring a value to another field (1 Viewer)

[icemonster]

so i have this form that creates a schedule and the way i made it work is that the time is being taken from another form. odd thing is when i type in the time (short time) it works, hours are calculated between the start and end time. but when the field's value is carried over to the form (Which on the other form is also short time) i get a mismatch. any ideas why? or is it because the value is carried over?
