Hi,

Is there a way to use REGEX to check a field to make sure it follows a specifi format with a delimiter?

The field will have alfa-numeric values but they must be 4 digits long with a comma seperation and no spaces.  There is no specific on how many groups of these alfa-numerics are allowed.  

These would be valid:

1xi4,GX19,Nn92

ZZZ1,8939,YXKE,791W

These would not be valid:

1x49d,GX1,Nn92

,1xi4,GX19,Nn92

1xi4,GX19,Nn92,

1xi4,GX19, Nn92
