Thanks for the response-

I want it to pull up the specific value in a line where I am double clicking on.

In this case, I click on row 3 and column "Refer2" where is the value A32A selected. And I would like that value to be passeed in Entryhead form into textbox Reref1?
Similarly, if I clicked the fourth line, column "Refer2", the value of R123 would be transferred...
