# Non digit character between brackets in variable

Dear all

While I was doing some operations that involve variables, I got the error “Non digit character between brackets in variable”. I was unable to debug it. I think the following snippet will be enough to find it:

code snippet:

variable maxplanevalue equal “v_ycy[1] + v_zcz[1] + v_cc”
variable maxatom equal 1
print "{maxplanevalue}"* <i>variable minplanevalue equal "v_yc*y[1] + v_zc*z[1] + v_cc"</i> *variable minatom equal 1* *variable tn equal {totalatoms}+1
variable a loop \${tn}

label loopn
print "{a}"* <i>variable thisplanevalue equal "v_yc*y[{a}] + v_zcz[{a}] + v_cc"</i> *print "{thisplanevalue}"*

corresponding log entry:

variable maxplanevalue equal “v_ycy[1] + v_zcz[1] + v_cc”
variable maxatom equal 1
print "{maxplanevalue}"* *223457.004536763* <i>variable minplanevalue equal "v_yc*y[1] + v_zc*z[1] + v_cc"</i> *variable minatom equal 1* *variable tn equal {totalatoms}+1
variable tn equal 13972+1
variable a loop \${tn}
variable a loop 13973

label loopn
print "{a}"* *1* <i>variable thisplanevalue equal "v_yc*y[{a}] + v_zcz[{a}] + v_cc"</i> *print "{thisplanevalue}"*
ERROR: Non digit character between brackets in variable (…/variable.cpp:2808)

Thank you
