Question : SMPTE time code input mask not working

Hi, I'm trying to build a home movie database and in the Film Length field I want to have an SMPTE time code input mask, but it's not working right. The input mask is in the form of: 99:99:99:99;0;_

Everytime numeric data gets entered into this field MS Access gives me a MSG box that reads -
-=-=-=- "The value you entered isn't valid for this field." For example, you may have entered text in a numeric field or a number that is larger than the FieldSize setting permits. -=-=-=-

I entered numerical data in every placeholder area, and random values each time - no matter what I've done it still gives me the error. It has lead me to believe that maybe this field has more options that I'm overlooking.

Answer : SMPTE time code input mask not working

That's why - a date/time field can accept a maximum time value of:
23:59:59

Your input mask has 4 sections, rather than the 3 that a time value permits:
99:99:99:99

You could change it to a text field, or if you're happy not to store the :, a numeric field.
