Hello,

I am need to field calculate sequential numbers starting with 033900000100191511. So, the numbering would be 033900000100191511, 033900000100191512, 033900000100191513 etc...

Can anyone help me with a python script for this?

With much appreciation,

Ana

Ok... that is an ugly one, since you are working with strings so the simplest thing is to increment from a know easy starting point and concatenate the string to it.

try these fixes

pstart = 511

return "033900000100191" + str(rec)

can't test it, so just select a few rows and try it and report back with a screen grab of the table if possible
