Hello Listers,

I have one character field.This field should contain 'characters and then
followed by numbers'.For example the field should contain the value of
'PRQ1234'.I am extracting the string after PRQ in a temporary field.So,the
temporary field will have value if 1234 in this case.But, if this temporary
field contains a value other than numbers,then the user should get a error
message.

How should i check if this  temporary field contains only numbers after
alphabets?

Please help me on this.

:confused:
