hI Dlanor i find a bug in the code
a) When i run first time the code and give for example Prefix D and first number 1 and last number 10 gives me thiis error text
Oops an Error : bad argument type: stringp nil occurred.
I dont't know why
b) After this error if i give Suffix D and first number 1 and last number 10 print
1D - 2D - 3D - 4D - 5D - 6D - 7D - 8D - 9D - 10D - 1D
c) Then i try the fist text again and give Prefix D and first number 1 and last number 10 and then print
D1D - D2D - D3D - D4D - D5D - D6D - D7D - D8D - D9D - D10D - D1D
Why didn't clear the Suffix from the memory ?
Any ideas ?
Thanks
