MS Access/ VBA : add if condition to vba code -


i have following code : 

private sub command66_click() docmd.setwarnings false docmd.deleteobject actable, "table1" docmd.deleteobject actable, "table2" docmd.deleteobject actable, "table3" docmd.setwarnings true end sub

the problem if "table1" not present,i receive vba/debug error. can add condition if script doesn't find "table1" should go further , delete other 2 tables without returning error message?

you mean error trapping? here's example of how can "trap" error - if error occured trying delete table1 ask if want continue:

private sub command66_click() docmd.setwarnings false  on error resume next docmd.deleteobject actable, "table1"  if err.number > 0     err.clear     on error goto 0     if msgbox("there error trying delete table1, want continue?", vbyesno) = vbyes         docmd.deleteobject actable, "table2"         docmd.deleteobject actable, "table3"     end if end if docmd.setwarnings true end sub
