Hi, Im trying to substract the last five digits out of a variable (@NUM_SERIE). Im using the math step as follows first im setting (manualy) '@NUM_SERIE' to '3C34567Z98712345' But on the [18] Math step Im not populating the variable (@N_SERIE_CINCO) Any hint? is there a step to get the 5 digits out of a variable but from right to left? thank you Feb 02 20:17:54.29: [106] Set Global Variable Feb 02 20:17:54.29: Setting global variable '@NUM_SERIE' to '3C34567Z98712345' Feb 02 20:17:54.29: [2] FINISH Feb 02 20:17:54.29: Main<==Defaults Feb 02 20:17:54.31: [55] Wait for Call Feb 02 20:17:54.31: WARNING: TIMEOUT '0' evaluates to 0 and is interpreted as no timeout Feb 02 20:17:55.81: Wait for 0 rings and then pickup Feb 02 20:17:57.64: Connection delay: 500 ms Feb 02 20:17:58.14: [106] Run Flowchart Feb 02 20:17:58.14: Flowchart: 'obtenerdatos' Feb 02 20:17:58.14: Main==> obtenerdatos Feb 02 20:17:58.14: [1] START Feb 02 20:17:58.14: [3] Clear TT Feb 02 20:17:58.15: [4] Get TT String Feb 02 20:17:58.15: Setting global variable '@CINCODIGITOS' to '' Feb 02 20:18:02.07: Got: '12345' Feb 02 20:18:02.07: Setting global variable '@CINCODIGITOS' to '12345' Feb 02 20:18:02.07: [7] Beep Feb 02 20:18:02.25: [8] Beep Feb 02 20:18:02.40: [18] Math Feb 02 20:18:02.40: @N_SERIE_CINCO = substr (NUM_SERIE, 12, 5) Feb 02 20:18:02.40: @N_SERIE_CINCO = substr (NUM_SERIE, 12, 5) Feb 02 20:18:02.40: (integer): 5 Feb 02 20:18:02.40: Setting global variable '@N_SERIE_CINCO' to '' Feb 02 20:18:02.40: [9] Compare Feb 02 20:18:02.40: @N_SERIE_CINCO = @CINCODIGITOS?

Here is your best bet: 1) Use a Math step to get the length of the @NUM_SERIE variable. (Set radio button to "String length of") 2) Use Math to determine the start position of the string to cut from @NUM_SERIE, as follows: The string length from step 1 minus the length of the string to chop, plus 1. (ie. if you know you want to cut 5 characters from @NUM_SERIE, take the length of @NUM_SERIE minus 5 plus 1) So, you might set a variable named @START_POS to hold this value. 3) Use Math to copy from @START_POS for the number of characters to copy. Set the radio button to "Copy string from...", and set "Base value" to the string to copy from (@NUM_SERIE), set "Modifying value" to the start position for the string copy (@START_POS), and set the "Number of characters to copy" to 5. For details of all the ways to use the Math step, or for additional help about the Math step, consult the TeleFlow help for this step.
