This expression works perfectly on many online regex test sites.
(1[0-2]|0[1-9]):([0-5][0-9])(\s*)(i?[AP]M)?
against this string, which is in a textbox.
01:30 AM
The textbox is a simple textbox. The string value has been thoroughly screened for extra spaces or whatever. It is simple '01:30 AM'
The regex control on my page fails. Many alterations attempted but this should work. There are no errors on the page at allout
Can anyone see the issue? Or know of a know bug?
Thank you,
