help with a function using Regex

I have the following function which is very close to my needs with one exception. It is currently including the
Colon, Ascii Char 058. I have made several attempts in trying to exclude that char with no positive results. If someone could point me in the right direction. It would be appreciated. I am interested in trying to understand out you going about structuring the pattern for what you want to include or exclude. Thank you in advance for your consideration.

"\d+"
simply means digests(Numbers) only
You can use [0-9]+

I made the change, and I see that this "\d+" is the same as what you provided, [0-9]+, I may have not expressed by problem correctly. example of the string I am working with his three numeric digits, Colon :, space, Alpha text.
How do I exclude the colon along with the numeric digits?

I do not know why the code does not exclude any character but numbers, but it is difficult to see with out the sample.
You may try this, but I doubt it will work.
[0-9:]+

Thank you, I appreciate it. It did remove the colon, there is a leading space [032], can you tell me how I can remove it as well. again thank you in advance for your help.

thank you Mike, It worked as well, still have a leading space [032], I would to get read of, however could work around it. thank you and go aggies.

thank you both, I did solve it by using trim(function(cell). that got rid of the leading space
