contracts/2.fc:48:5: error: undefined function `dictval`, defining a global function of unknown type
dictval~udict_set_ref(128, value, msg);
^
lvalue expression constructor is 8
fatal: cannot compile lvalue expression with unknown constructor

Does anyone know how to fic this

in this case, dictval is only defined inside of if {} or else {} block. it's not visible outside of it.

you can define it before if (), and then just set the value in it

so would i just do like cell dictval = 0? because just cell dictval; gave an error

you can do cell dictval = null()

is there a way to set integers as value in dictionaries, or a way to convert form slice to int and back

values are always slices. you can simply store a single integer in a slice if you only need it in a value.

int to slice:
int value = 123;
slice slice_from_int = begin_cell().store_uint(value, 256).end_cell().begin_parse();

slice to int:
slice value = {{{dict get or something else}}}
int int_from_slice = value~load_uint(256)

oh ok
