I read about a clever use of the Instr function along with a criteria to select subsets of records. An additional calculated field is added with the syntax = "InStr(1,[Enter Full WP Numbers separated by commas,Blank=All],[tblOrigBudg].[WP])" (without quotes). In the criteria field you put ">0 Or Is Null" (without quotes).
When executed, you can enter the variable (wp in this instance), and it returns the recordset. It works most of the time, but I have a situation where when I ask for 'F1.13', I also get 'F1.1'.
How can I correct this?
