Calculating Time in Userform Textbox and Filtering Comboboxes Coding Help

Is this something that is even possible?

You would need to add code into each start/finish textbox to update the values in the Hours/TotalHours textboxes. Forms in Excel do not do auto-calculate. You need to tell it to do that.

As for Account Description, you would need to have the Account Code update event(s) regenerate the rowsource. You probably need to set the rowsource to "" and then give it the appropriate rowsource. I am not 100% sure on this because I am going from memory and I haven't had to work with combo boxes in Excel in a while.

I have been trying to create a code, but I am not sure because it is not working to calculate the hours. I am so new to VBA and userforms, so my codes probably make a seasoned coding guru cringe, lol. Is that code going to be in the textbox private sub or the part where everything is?
You are speaking complete gibberish to me, it is as clear as mud talking about the Account Code

Please take the time to read through some VBA tutorials. Here is a short list that you might find helpful.

Essentially, every object on the form has some sort of "events" that you can add code to to get things done. The most used event is the "Click" event. The user clicks on a button and your code runs. But other events include things like "Change" and "Update" and "Activate", etc. The event you are interested in here is the Update event. For each of the start/finish textbox controls you have, you need to add code to the Update event to calculate the value for the appropriate Hours textbox.

Thank you, that is what I needed, was to know what type of event I was needing to use. Much appreciated I will move on from here
