Hello, 

I have developed a PDF form and I need help solving a simple problem. 

 

I have a "Last Name" field at the top of my form and I need to pull the first 3 letters from that field into a different field at the bottom of my form. 

 

For example: 

Last Name; SMITH

3 Letters: SMI

 

I have tried substrings and calculations but I can't get anything to work...

 

Please help! 🙂

Correct answer Thom Parker

Put this in the calculation script for the field that gets the first 3 letters

 

event.value = this.getField("Last Name").valueAsString.substr(0,3);
